SIP SRST with 3905

Hi I have SIP srst with 3905 and 6921. 6921 Phones are getting registered as expected with SRST gateway. but 3905s not like that. i need to restart (re-plug) the phone manulally, then they will register with SRST. what will be the reason for this ?

is this a bug ?

Re: SIP SRST with 3905

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


http://www.cisco.com/en/US/docs/voice_ip_comm/cusrst/admin/sccp_sip_srst/configuration/guide/srst_41.html

http://www.cisco.com/en/US/docs/voice_ip_comm/cusrst/feature/guide/srst71ft.html

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

have you tried one of the 3905 on a lower FW ver like 9-3-2 or something and see if you get the same issue.
