[cisco-voip] CME-SRST question

[Ahmed Abd EL-Rahman]

Thanks Tommy, but does your router flash has all CME TAR file contents extracted into it ? or nothing in the router flash with just these CLI commands ? also what type of SIP phones do you have ?

Hi Ryan,

Please find needed info in the attached file, also find the output of debug ccsip messages while a SIP phone tries to register (or it should be trying) to the CME-SRST, (phone IP: 10.90.11.54, Router interface IP: 10.90.241.100)

Another question, do I have to have all the CME tar file contents extracted to the router flash just for the CME-SRST functionality to work ?

Also if anyone have a working configurations for CME-SRST or even SRST with SIP phones, please share.


Many thanks

Can you send us the output of:

- # sh run | sec voice service voip|voice register|dial-peer voice|tftp-server

-# dir

Additional questions:

- What is the model of SIP phone?
- What CUBE hardware platform?
- What IOS / IOS-XE code version?
Thanks,

Ryan

Dear Gents,

I have a setup of CUCM 10.5 in a central site with a router in a branch site, phones in branch are registered with the central site CUCM and in case of WAN failure the branch site router should handle the branch phones till the WAN is up again, I have configured the branch router with CME-SRST configurations which is working fine with SCCP phones and all tests were successfully during WAN outage, my issue it with branch SIP phone which are not able to register to the CME-SRST router during WAN outage despite I have followed many configurations scenarios for SIP phones including global register configurations.

So does anyone have a working scenario configurations for CME-SRST (not unified SRST) working with SIP phones.
