Cisco Phone 8811 call-manager-fallback not register.

Hi,

I've five Cisco Phone's 8811 model and an isr 4300 with the "isr4300-universalk9.16.09.03.SPA.bin" Software image.

I have configured the call-manager-fallback for the esrst, but when I try to connect the phones They did not register.

This is part of the configuration:

How Can I resolve it ? Is there an incompatibility between the phone model and the router ?

With the "sh call-manager-fallback" I see this:

Re: Cisco Phone 8811 call-manager-fallback not register.

For SIP SRST / ESRST, do you have the SIP IP set in CUCM. Its an extra field in the SRST config, so the IP needs added twice.

Verifying SIP Registrar Configuration
To help you troubleshoot a SIP registrar and voice register pool, perform the following steps.

debug voice register errors
debug voice register events
show sip-ua status registrar

Also, try using show voice register all instead of show call-manager-failback.

Re: Cisco Phone 8811 call-manager-fallback not register.

The 8811 phones are SIP phones, so you wouldn't see anything under telephony-service. Instead, the phone would register to voice register global, which is SIP SRST.

I'm concerned about your statement that the 8811 phone won't "register". Do you mean that it won't fail over? To test SRST, the 8811 phone would need to be registered to CUCM and will have to have learned about its SRST Reference via its Device Pool. Then you can "break" the connection between the 8811 and the CUCM servers and watch it fail over.

With the voice register pool you have configured, it will only accept registrations from phones in the IP address range 192.168.30.128/25 so be sure the 8811 is in that range when it goes through the failover process.

When you are ready to test failover, you can run debug voice register events on the router and watch the failover/registration to the SRST process.

Let us know if you have questions, and let us know how this goes.

Re: Cisco Phone 8811 call-manager-fallback not register.

Hi,
As @Maren Mahoney has mentioned, consider those items and also try below commands. I had similar issues and this configuration resolved it:

voice service voip
sip
registrar server expires max 600 min 60
!
sip-ua 
registrar ipv4:192.168.30.129 expires 600
!
