Question

what is the bandwidth requirement of cisco 9971 model phone during registration?

Answer 1

Thanks a lot Vivek... I went through it...but I think it talks about the bandwidth provisioning for voice traffic..for signalling and once the call is established....I neeed to know the bandwidth required just for registration ...i.e. in the following steps ( only registration without placing any call)   
1. The phone contacts the TFTP server and requests the Certificate Trust List file .
2. The phone contacts the TFTP server and requests its SEP<mac-address>.cnf.xml configuration file.
3. The Phone downloads the default configuration XMLDefault.cnf.xml file from the TFTP server.
4. The SIP phone requests a firmware upgrade (Load ID file) and upgrades the firmware image automatically when required for a new version of CUCM.
5. The phone downloads the SIP dial rules configured for that phone.
6. The phone Establish connection with the primary CUCM and the TFTP server end to end.
7. The phone Registers with the primary CUCM server listed in its configuration file.
8. The phone downloads the appropriate localization files from TFTP.
9. The phone downloads the softkey configurations from TFTP.
10. The phone downloads custom ringtones (if any) from TFTP.
Also, I need t o know if the bandwidth required for this process is same for all phone models or different? Specifically, I need  this data for Cisco 9971 model.Please help...Thanks..
