3905 phone won't register with srst gateway

[Gramirez23]

Hi Fellows

i got an issue, if you could help me would be great. I have a bunch of 3905 in a remote office and when loses connectivity with the call manager won't register with the local gateway, i check the phone and in the telephony information shows me active server:<ip_publisher> and stand by server: <ip_subscriber> and does not have the option to put a third srst server.

I reviewed the pre requisites in cisco's web site and seems all in order

http://www.cisco.com/en/US/docs/voice_ip_comm/cusrst/requirements/guide/srs88spc.html

Version of the firmware phone : 9.2.1.0

Version of SRST : 8.8

Version of GW IoS : 15.2(1)T

Version of CM: 8.5.1 SU2

Thanks in advance

Best Regards

Hi,

Could you please post your SRSTSconfiguration? Since you need SIP SRST in order to re-register these phones to the GW, please check these links:

Fellows,

The solution was to put configurations related to sip, these are the lines that i added

********* Enable SIP srst register **************

voice register global

system message XXX

max-dn 20

max-pool 20

********** Create the endpoints that are going to register with the gateway ************

voice register pool  1

id mac XXXX.XXXX.XXXX

number 1 711

codec g711alaw

********* SRST related **********

application

global

  service alternate Default

sip-ua
