Level 1

Hi,

We have experienced registeration problem in SRST mode for IP phones that have sip firmware. Sccp ones registered properley. I can monitor sccp phones with "debug ephone" command  when they register or unregister, But Sip phones dont even try to register on router. Could you please help if I miss something in my config. 

CUCM version : 8.5

2801 Router IOS: 15.1.4M10

SRST version : 8.6

SCCP Phone firmware version: 9.1.1

Sip phone firmware version: 9.1.1

Endpoints,Router and CUCM -> all in same subnet.

I have also attached router config.

Phones used: 7942, 7911

Thank you.

Probably the missing thing is come srst. But There is no mode srst in selection. Router just allow me to set mode as cme. Like below;

Antalya-2801(config-register-global)#mode ?
cme CME mode

Thank you guys for your answers and care.

Hi ,

can u share show version of router along with output of show call-manager-fallback?

As a side note besides what my friends already have mentioned, can you cross verify that you have configured SIP Nework/IP Address as well under SRST reference in CUCM, as there is separate IP address for SCCP and SIP phones.

- Vivek

In my first configurastion SIP Network/IP Address was blank. But yesterday i have added it as the same Ip address with sccp SRST ip adress. 

Hi Yavuz,

I am not able to find the reason why it is not appearing . May be it is default.

Can u try putting command proxy x.x.x.x preference 1  where x.x.x.x is IP address of CUCM under voice register pool 1

What is the count of total SIP and SCCP phones?

regds,

aman

This is a lab scenario so there is one sip phone 7942 and one sccp phone 7911. But the main goal is to apply this solution in my customer site which have around 1000 sip phone and 300 sccp phones.

I have added proxy ip address. Still not registering. Now its look like ;

voice register pool 1
id network 192.168.90.0 mask 255.255.255.0
proxy 192.168.90.100 preference 1
no digit collect kpml
dtmf-relay rtp-nte sip-kpml
voice-class codec 1

Thank you.
