Hi All
I am hoping you can help me with a problem that I am facing with sip trunk registration. I am newbiee to setting up CCME so please bear with me
Scenario: Have a Cisco 1861 router running c1861-spservicesk9-mz.152-2.T1.bin on which i have installed CCME
The router is also acting as my home ADSL router. I have 2 hard phones plugged into it and both phones register and I can all each other internally no problems. Both Cisco phone are running SCCP.
I have setup a SIP trunk with voipdiscount.com and when I reboot the router the SIP trunk come up automically and I have configured CCME for outbound call only at this time and it all works fine.
Version of CCME
Version 9.0
Max phoneload sccp version 17
Max dspfarm sccp version 18
Cisco Unified Communications Manager Express
Problem: After about an hour or so of no activity the SIP registration drops and when I try to make any outbound calls I just get the engaged tone. When I run this command it show the registration as down.
Cisco1861#show sip-ua register st
Line peer expires(sec) registered P-Associ-URI
================================ ========== ============ ========== ============
5001 20001 119 no
5002 20002 119 no
5003 20003 120 no
rka61xxx -1 119 no
rka61xxx is the SIP trunk
Workaround: Only way to bring the SIP trunk back up all I have to do is ping the sip trunk I am using
Cisco1861#ping sip.voipdiscount.com
Translating "sip.voipdiscount.com"...domain server (8.8.8.8) [OK]
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 77.72.169.131, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 48/49/52 ms
Cisco1861#ping sip.voipdiscount.com
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 77.72.169.131, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 52/52/52 ms
Then if I wait a minute and then run this command the SIP trunk is back up
Cisco1861#show sip-ua register st
Line peer expires(sec) registered P-Associ-URI
================================ ========== ============ ========== ============
5001 20001 2847 yes
5002 20002 2846 yes
5003 20003 2847 yes
rka61xxx -1 2846 yes
Now I can make outbound calls. But if I make a call and hangup and make another call I get the engaged tone and the SIP trunk goes down again.
I do not know why this is the case and have to ping it again to bring it back up as you can imagine this is very frustrating. I have contacted my SIP provider and they do not state the problem is at there end. These are the SIP details to use http://www.voipdiscount.com/sip

I would really appreciate any tips and pointers from anyone. My end goal is to have the SIP trunk registration stay up so I can make outbound calls and not have to ping to bring the trunk up after every call.
Many thanks in advance for you help

Hi All
After reading some of the forums I found this discussion sounds very similar to my issue do not know if it is bug in the IOS

If someone could please confirm my suspicion.
