SIP TRUNK BETWEEN TRIXBOX AND CME

[Jesutofunmi O]

Hello Guys,

I have a Cisco CME with about 40 phones on LAN (site 1) which can call each other properly without any issues (over the LAN network). I have a functional VPN to a remote site. The remote site (site 2) users use Trixbox for their own LAN communication. Now, I wish to establish a SIP trunk between the CME and the Trixbox so both site can call each other. Has anyone done this before? Please assist with a configuration guide. I am not confident of the ones I have seen online and there are very few materials out there for this type of deployment. Please note that I am beginner in SIP.

If you know how to create dial-peers, then all you need is a SIP VoIP dial-peer pointing to the Trixbox.

[Dennis Mink]

on your cme point a dial-peer with the DN pattern of your remote site for example 1...  and use sip on the dial peer. point trixbox to your cme in the same sort of fashion.

[Jesutofunmi O]

Alright, thanks. I'll do just that.

Hello Guys,

I have been able to configure the CME to call Trixbox successfully but Trixbox is unable to call CME. Also, I intend to trunk from CME to other boxes but I am unable to create multiple SIP registrars as I keep getting the error below when I try it 

POHT (config-sip-ua)#registrar 1 ipv4:192.168.2.25 expires 3600
Primary-Secondary mode currently configured; Cannot configure multiple registrar

This is my CME Config

1. You can configure upto 6 registrars. You need to change the index, you already have a registrar for index 1.
2. Collect logs for a failed call -
debug ccsip message
debug ccsip error
debug voice ccapi inout

[Jesutofunmi O]

Hi Nipun,

Thanks for your response. 

1. I removed the registrar and I could still call the trixbox only with the dial peer. But the trixbox is still unable to call CME. When I try to add more registrars, I get the error message below;

*Primary-Secondary mode currently configured; Cannot configure multiple registrar*

Please, how can I place the CME in a mode to accept more than 1 registrar?

2. Does this mean I cannot add multiple dial peers (multiple trixboxes) without adding multiple registrars?

And if I may ask please, what is the difference between the registrar server and a register server?

[R0g22]

Share output for "show run | s sip-ua"

[R0g22]

Registrars are used for SIP end points registrations. With dial-peers you govern call routing. You only need registrar if you are trying to register something to the registrar IP in this case would be your CME. Does your trixbox require this ? If not, you don't need registrar.

[Jesutofunmi O]

Nipun,

Below please;

#show run | s sip-ua
sip-ua
registrar ipv4:192.168.0.120 expires 3600
sip-server ipv4:192.168.0.120

 I get the error message below when i try to create multiple registrars

*Primary-Secondary mode currently configured; Cannot configure multiple registrar*

[R0g22]

Like I mentioned in my other post, you need to index the registrar servers. Something like -

registrar 1 ipv4:1.1.1.1
registrar 2 ipv4:2.2.2.2

You configure upto 6 Registrars but you need to understand if you need a Registrar or not. Read my last post.

[Jesutofunmi O]

Hi Nipun,

I have been able to create multiple registrars but;

1. Still unable to make call to the other peer 192.168.2.25

2. Still unable to make calls to CME from either of the peers 192.168.0.120 and 192.168.2.25

Calls from trixbox (192.168.0.120) to CME works just fine. Kindly help look into the error messages received from debug. I made a call to an extension of 192.168.2.25 and took down the error messages. 

[R0g22]

I don't see a single call in the logs. Do the following first -

logg buff 5000000 deb
no logg con
no logg mon
no logg trap
no logg source
logg on
do term no mon

Post above, enable the following -

debug ccsip message
debug ccsip error
debug voice ccapi inout

Once you have made the test calls, increase the scrollback buffer of your telnet client then do the following -

term len 0
show logg

Copy the logs in a text file and send across.

[Jesutofunmi O]

Hi Nipun,

Please find attached.

Thank you.

[R0g22]

What scenario were the logs collected for ? Calls from CME or calls to CME ? I still don't see a call.
