What is the issue you are running into?

Couple of quick observations:

Is the ID network correct? Proper mask?

Why is the mode esrst? E-srst is managed SRST, is that what you have?

[Akaffou Aristide Akaffou]

Hi Chris,

In my router I have two options(mode cme and mode esrst).

I confirm that the ID network and the mask is correct.

Have you configured the ff in CUCM

UCM SRST reference:

SIP Network/IP Address :

SIP Port 5060

Can you also remove this..

source-address <158.113.41.84:ip address of the CUCM server> port 5060--This is not required. You can also remove the load commands..

[Akaffou Aristide Akaffou]

Hi Ayodeji,

please share me the good configuration about sip srst, because I'm in trouble with it. I think we don't have so many documentations about it.

Please share me your experience.

Regards,

Aristide

Here is a template you can use..

it looks like you are missing the sip-ua config..

voice service voip

sip

registrar server expires max 600 min 60.

voice service voip
 allow-connections sip to sip

sip

  registrar server expires max 600 min 60

!

voice register pool  10
 id network 172.26.10.0 mask 255.255.255.0
 dtmf-relay rtp-nte cisco-rtp sip-notify
 codec g711ulaw
 no vad
!
voice register pool  11
 id network 172.26.11.0 mask 255.255.255.0

 codec g711ulaw
 no vad
!

sip-ua
 registrar ipv4:172.26.10.240 expires 600

(172.26.10.240 is the SRST gateway IP address).

### CUCM CONFIG ####

On UCM SRST reference configuration for gateway

SIP Network/IP Address 172.26.10.240
SIP Port 5060

Thank you Ayodejipo I will try it.

[Akaffou Aristide Akaffou]

Thank you Ayodeji,

the srst configuration works fine, but I have another issue. The IP phones won't register in CUCM, I think there is a routing issue, because when I try to ping ip phones from the CUCM, it marks destination host unreachable. Please can you help me?

In attached you can see the screen capture of ping request.

Thanks for all guy.

Akaffou
