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 ?

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/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.

Hi
No i'm not, because there are lot of bugs in prevous FW version. So thats why i upgraded it to latest. if I downgread it other bugs will eb hit to phone.

Few things you need to check.
Are you able to see SRST ip on Phone as secondary server ? - NO(check on cucm device pool and SRST reference) - Yes - Then put a packet tracer on phone switch port and see "Proxy slot #0 () - De-registering AOR" message floats when WAN goes down or you only see continuous keep-alive message exchanging ? Do you see any Registration request goes to SRST ip from that phone ? -No (then it look line phone firmware issue) - Yes - Then check your SRST router, did you see request from phone IP by enabling "debug tftp event"-Yes - Then check SRST version on router , does it supports IP Phone or its updated firmware - Yes- Recheck you SRST configuration for SIP.
