VXML on the AS5350

I am implementing an IVR system using the AS5350 and I am sure that I will have a bunch of questions about the details of the implementation of the VXML 2.0 spec within it. Is there an active forum other than this one that is set up to address this?
Are the conformance scripts available anywhere online? I have seen the conformance table:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/rel_docs/vxmlprg/refgap2.htm
But I was interested in the scripts that were used to prove conformance. Having those available online would help to answer a lot of questions people like me might have.
Thanks.

Thanks, That is a good document and one I have used.
The set of documents provided by Cisco are good, I was just trying to forestall any questions that will probably arise out of using features that are not "Exampled" in the docs you referenced.
To be VXML 2.0 "compliant" I would assume that they have to have a set of scripts that exercise the browser. There is one such set at:
http://www.voicexml.org/conformance/samples/
but it is a generic set and not of much use beyond the simple stuff. I would think that the publishing of the scripts that Cisco uses would be usefull to all of us. They might however feel that they are proprietary.
Thanks
Paul.

CVP: using the Gatekeeper and the SIP Proxy, why? VXML gateway and the ingress gateway communication?

Hi All;
I am actually keep asking with my self, why to use gatekeeper or SIP proxy when deploying the CVP solution, why not to use the Call Manager? Is it because that the concept built on SIP and H323 so call manager can not handle these kind of operations as call manager is supporting MGCP?
From the other side, what kind of trunk or protocol of communication method is used between the ingress gateway and the VXML browser?
Any advise?
Regards
Bilal

The main reason is not all who deployed ISN/CVP in the past use Call Manager as the PBX.
CVP is a powerful solution that covers many deployment scenarios. Its ability to integrate with legacy switches has been very important in the past, and although as we move forward, these types of deployments will probably become fewer, the independence of CVP on Call Manager remains a cornerstone of the design.
I'm glad it was built that way. Look at some of the other deployment models (like Call Director) in the CVP Guide.
It's not because Call Manager supports MGCP - you don't need to have any MGCP gateways in your Call Manager deployment. You could have all H.323 gateways and manage the dial plan on the gateways with a gatekeeper. Or use SIP.
The ingress gateway does not talk to the VXML server - the VXML gateway does.
In a branch office design, these are one and the same; but that's not the fundamental architecture. The IOS on the VXML gateway runs a voice browser (I guess you could call this a VXML browser). It uses HTTP to send and receive information (VXML documents) from the VXML server - whether this be the CVP Call Server or an external VXML server (like what was brought in-house with the Audium acqusition - the Cisco CVP VXML Server).

Maximum num-exp that can be used on AS5350

I was told the AS5300 has a maximum num-exp of 256. However, the AS5350 had better capabilities and should do more.
Does anyone know the maximum amount of num-exp that can be configured on an AS5350?
Thanks,
~J.K.

As many as the routers memory and nvram (for config save) can hold. Note that having numerous num-exps and translation patterns are sensitive to faults...

Configure AS5350

how do you configure the as5350 to collect cdr records into a server? what commands do you use?

AS doesn't coolect CDR's, server does (ART app).
For other calls (typically data, not going trough server) radius or syslog with some debug (bad solution).

VXML and grammar types

Hi folks from a new member,
On a UCCX v7.0, we have serious trouble getting GrXML grammars to work with VXML code. We have extensive experience with other IVRs (WVR, Prophecy, GVP) but Cisco's IVR seems idiosyncratic. Our Nuance is v10, so we have defined grammars as "OSR v3.1.x" as instructed by a Cisco manual (which mentions that "Nuance" grammars must be defined for Nuance v8.5 and "OSR v3.1.x" must be defined for Nuance v9 or newer).
Our current code looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<vxml version="2.0" xmlns="http://www.w3.org/2001/vxml" xml:lang="el-GR">
        <form id="Welcome">
                <field name="Menu">
                <prompt bargein="true">
                        <audio src="./prompts/Hello.wav"/>
                </prompt>
               <grammar mode="voice" version="1.0" xml:lang="el-gr"
                    type="application/srgs+xml" src="http://192.168.0.110:8087/Sample_MTS/grammar/YesNoAgent.grxml"/>
...and immediately gives a "grammar not supported" error, without even asking the application server for the grammar URI (as we can confirm in the Tomcat logs). The grammar looks like this:
<?xml version='1.0' encoding='UTF-8'?>
<grammar version="1.0"
         xmlns="http://www.w3.org/2001/06/grammar"
         xml:lang='el-GR'
         mode='voice'
         tag-format='swi-semantics/1.0'
         root='Service'>
<rule id='Service' scope='public'>
    <one-of>
      <item>
        <one-of>
...and so on
I would creatly appreciate it if some kind soul posted a sample VXML (just the grammar fragment) and GrXML code that is known to work. Same for calling more complex grammars that are compiled into .gram format.
Thanks a lot,
George

A simple "Hello World" vxml script for a Cisco IVR gateway would be...
<?xml version="1.0" ?>
http://yourwebserver or flash/hello_world.au"/>
Unless you have a compatible Nuance text-to-teach server you have to use pre-recorded audio that is servered up internally from the router / gateway's flash or from an external web server. The audio must be in a very specific audio format with an "au" extension or you won't hear anything.
You must have an IOS version and hardware platform that supports VXML obviously. The vxml browser is built-in to the code. You place the application either on the router / gateway or on an external webserver and add it into the IOS dial-peer configuration.
There is a VXML 2.0 standard and than there is what Cisco says that the IOS VXML supports with 2.0 and then there is what really works. And then there are the differences on what works on one hardware platform and not the other. It takes a lot of experience and effort to get a working VXML IVR application if you are doing anything complex.
The good news is that IOS VXML works with php, javascript, etc. so it is possible to do complex scripts and have it interface with outside data.

IVR VXML Interpreter problem

Hi,
we are developing a VXML application invoked from IVR VMXL interpreter. Our problem occurs when we want to use # key. The poblem is when wue press this key the VXML interpreter ignore this. If we associate the same action to the * key it works fine. The problem is related to # key.
Is this key reserved from IVR VXML interpreter?
Has anyboby experienced this issue?
My CCX/IVR version is 7.01 SR5.
Could anybody help me?
Regards

In the VXML standard, the # key (pound in the US, hash in the rest of the world) is defined as the termination character (termchar) for DTMF entry. If you are asking callers to enter (say) an account number which has between 5 and 8 digits, you need to know when they have finished. The normal thing to do is to allow them to enter # to say that they have finished.
I strongly suggest you don't use this key for another purpose.
But if you do need to, you must tell the VXML browser that the key does not have the usual role. The syntax is defined by the VXML standard. You can set the termchar to empty as follows;

Downloadable IP ACL with AS5350

with the installation of the newest ACS, for Radius authorisation the use of downloadable IP ACLs has been implemented.
However on the AS5350 I see that it does n't recognise this feature (I'm using the IOS 12.4.12, following the cisco site this feature should be known)
Can anybody tell me what I do have to configure on the AS5350, so that it recognises this attribute
ON the cisco site, I cannot find any link between these ACLs and the AS5350.
Thanks for helping me.
Ellen

Ellen,
On 5300 we need min IOS IOS 12.3(8)T or later to support it. I'm not sure if we have code for AS5350.
If you'd like to see some examples, here is a link which sort of describes some examples
of what the radius av-pair looks like.

Frame Relay and as5350

Dear Experts,
we got a 2811 framrelay hub ,which also runs VOFR ,since the device is not fully compatible with our PBX we decided to replace it with an As5350 ,but unfortunatley the as5350 does not support VOFR , is there any way to configure Vofr on as5350 with ios upgrade or any other way?
if not , is it possible to configure a 3640 router as the hub router wich runs VOFR ,and also configure the 3640 as a gatekeeper to route the calls to as5350 for termination and vice versa ?
all suggestions are welcomed,
Farshid.sh

Hi, as you noted the 5350 doesn't support VoFR. You can only terminate VoFR on other models, having the 3640 doing GK would not help, because GK is for VoIP only.
Hope this helps, please rate post if it does!

AS5350 Redundency (two ethernet ports) ?

Hiya,
The AS5350 has two ethernet ports. However, I am unable to find supporting information as to why ?
I assume it's for redundency. However, how do Cisco recomend to design VoIP redundency within this AS5350 ? i.e connect two ethernet ports to two different ethernet swicthes.
HSRP is not the correct tool for the job here.
.......... uhhmm, so what's the secret ?
Thanks for reading
Matt C

This can be used as redunant ports only ion case of failure of another. But this should not be confused with a switch port which will be working as a redundancy. Here u have to configure manulayy other port if one fails.

As5350 fax problem

I have a Cisco As5350 voice gateway with 4 E1 interface. It coneects to a remote AS5300 gateway by Internet . When the as5300 sends a fax to as 5350 ,it's ok ! But when as5350 sends one to as5300 , it will disconnects when they are handshaking .
The as5350 is configured as fax protocol t.38 & fax rate voice & fax-relay ecm disable.
What's the problem ?

The as5350 can work with T.38 only, hence you have to configure as5300 with T.38. And you also need to configure the incoming dial-peer on the as5300 as T.38
The additional configuartions on as5300 should be :
dial-peer voice 200 voip
incoming called-number .T
fax protocol t38 ls-redundancy 0 hs-redundancy 0
Also check if the codec and the clocking and compression techniques used are same, on both the ends.

Clear type ahead buffer in VXML - Call Studio 8.5

Hi,
I'd like to take control of the type ahead buffer within my VXML script developed in Call Studio.
So far the only thing I could find about it is a reference to a VXML prompt attribute, but nothing about how it can be set in Call Studio. Has someone successfully used this? If yes, can this be set within Call Studio?
Thanks,
Attila
http://www.cisco.com/en/US/docs/ios/voice/vxml/developer/guide/refgde1.html#wp1049198 says:
"cisco-typeaheadflush Attribute for <prompt>
The default value of cisco-typeaheadflush is false. A false value means that the typeahead buffer is not flushed after the prompt plays out. If the prompt is bargeinable, the digit which barges in is not flushed.

I've tried configuring it in the settings tab just like you had on the screenshot with both com.cisco.typeaheadflush and the cisco-typeaheadflush too.
Unfortunately the non bargeable prompt is still skipped after a bargeable prompt having those set.
Shall I be thinking of writing my custom Audio element for this?
This is the generated VXML by the way:

AS5350 dialer

I have a syslog server, an AS5350 dialer and some remote users.
I'm trying to log hosts/hostnames to my syslog server from the AS5350.
There are users at home dialing in to our private network via the AS5350. What command(s) is/are required so that I can log host information to my syslog server from the remote users who are accessing my network through the dialer?
Any help would be appreciated.
Thanks.

I think logging command in order to enable or disable informational messages to the console sends to a syslog server. And also try this command dialer mult-map-same-name

AS5350 and CCM integration

Hi
I dont see the AS5350 on the CCM gateway addition page. is this device supported on the CCM? or do I have to do a workaround? if so what must i do?
Thanks in advance

You can configure AS5350 as H323 gateway for CCM.

AS 5350 XM software upgrade

Dear Networkers,
Woe have UCCE solution installed. We are using AS 5350 XM as Egress and VXML Gateways. We are planning to upgrade the whole UCCE solution to 8.5 and we need to upgrade the IOS of the AS5350 gateways to 15.5T. Do we need to purshase licenses ? I mean : do we need to purshase licesne to activate the VXML feature on IOS 15.5T or just do the IOS upgrade ?
Thanks in advance.
Best Regards.

Only IOS update.

Slow ARP response for dial-in clients

I’ve been experiencing an intermittent issue with remote PC’s connecting to a Cisco AS5350 Universal Gateway - basically, a RAS server.
The issue as far as I’ve been able to pinpoint seems to be related to the amount of time it takes the dial-in client to register an ARP entry on the local network where the RAS server and other servers are connected.   If I start an extend ping to one of the servers on the local network (not to the RAS server) once my dial-up connection has been established, I typically see anywhere between 3 and 18 ICMP request timeouts before I start receiving replies. And if at the same time I start an extended ping to the IP address of the RAS server, ICMP replies are received immediately with no request timeouts.
Topology:
Dial-in Client <===> AS5350 RAS <===> L2 Switch <===> Server
192.168.240.131         240.5                           240.1               240.21
The switch that the AS5350 and the servers are connected to is a WS-C2960G-8TC-L layer-2 switch with a very basic config. Basically they only thing I’ve changed during the course of my troubleshooting is the STP mode, STP forward time and to enabled STP portfast on the uplinks to the AS5350 and the server… see configuration below:

For troubleshooting, I enabled “debug arp” on the switch and attempted a dial-up connection to the AS5350. Once the call was established and I received a DHCP lease (192.168.240.131), I started an extended ping to a server (192.168.240.21) on the network… see below:

The first line of the debug shows the switch creating an “incomplete entry” for the dial-in client (192.168.240.131).
For all subsequent ICMP requests, you can see that the dial-in client has a MAC address of 0000.0000.0000 – I guess you would call this an incomplete entry.
On the last line of the debug output, you can see that the dial-in client (192.168.240.131) finally gets the MAC address of the AS5350 (000d.280c.fe1b) assigned to it – this is when we start getting ICMP replies.
So during this capture, there were 12 ICMP request timeouts before the dial-in client started receiving replies.

Is anyone aware of an IOS bug or an error in my configurations that could be causing the delay in creating an ARP entry for the dial-in client?
I am open to any suggestions.
BTW, if I add static arp entries on the server, ICMP replies are typically received after one or two request timeouts.
However, I feel this is not a solution to the problem, only a band-aid fix.
