Hi everyone,
I have a CUCM and a Router 2901. I trying to deploy an SRST for SIP and SCCP phones simultaneously. I've put the following configuration, but only SCCP devices work OK. SIP Phones don't register in my router when CUCM is unavailable.
On Router:
#voice service voip
allow-connections sip to sip
sip
registrar server
#voice register global
max-dn 100
max-pool 42
system message ##Em modo SRST##
voice register dn 1
number 2001
voice register pool 1
id network 10.232.232.0 mask 255.255.255.0
call-manager-fallback
max-conferences 8 gain -6
transfer-system full-consult
ip source-address 10.1.23.216 port 2000
max-ephones 42
max-dn 100
On CUCM
port: 2000
ip address: 10.1.23.216
SIP Network/IP Address: 10.1.23.216
SIP port: 5060
Please help me with this.
Regards!!!

Hello Terry,
Thanks for your advice, now I can see that my SIP and SCCP Phones register correctly into my SRST Router when WAN outage happen. But I am facing with another problem, what happen is that When SIP and SCCP phone register into SRST Router, They both can't make calls between them. They can ring each other, but I there's a problem with RTP traffic, so endpoints can't hear between them. Do you have any advices for me?
Thanks a lot!!!
