Problem with fax rely bitween two Cisco 5350

Question

I have two cisco 5350 with the following setting:
Originating cisco :
voice service voip
fax protocol t38 ls-redundancy 3 hs-redundancy 0 fallback none
dial-peer voice 1 voip
huntstop
destination-pattern 111
session target ipv4:xxx.xxx.xxx.xxx
tech-prefix 011
fax rate 4800
fax protocol t38 ls-redundancy 3 hs-redundancy 0 fallback none
no vad
Terminating cisco :
dial-peer voice 71 voip
huntstop
incoming called-number 111
fax rate 4800
fax protocol t38 ls-redundancy 3 hs-redundancy 0 fallback none
no vad
voice service voip
fax protocol t38 ls-redundancy 3 hs-redundancy 0 fallback none
So using such settings i can not send faxes.
How can i find the problem ?

Answer 1

Hi,
I tried to use ls-redundancy 0 but - no result. When the faxes tring to connect to each other - i can hear the tones, but it looks like short tone and then silence.
Also i use the following commadns to solve the broblem:
-fax nfs 000000 at voip peer, fax interface-type and fax interface-type fax-mail. But no result also.
