SIP trunk between CUCM and CME

Hi guys,
Here is my config of SIP trunk between CUCM and CME (diagram is attached).

[I]dial-peer voice 168000 voip [/I]
[I]description **OUTGOING CALLS TO SYD OVER WAN** [/I]
[I]destination-pattern 168... [/I]
[I]session protocol sipv2 [/I]
[I]session target sip-server [/I]
[I]! [/I]
[I]dial-peer voice 169000 voip [/I]
[I]description **INCOMING CALLS FROM SYD OVER WAN** [/I]
[I]session protocol sipv2 [/I]
[I]session target sip-server [/I]
[I]incoming called-number .[/I]
[I]! [/I]
[I]sip-ua [/I]
[I]registrar ipv4:192.168.10.5 expires 3600 [/I]
[I]sip-server ipv4:192.168.10.5[/I]

The diagram and trunk, route pattern configs are on the screenshots.
The calls from 168XXX to 169XXX are dialed successfully and connection is established if dialed from CME to CUCM. However, the calls from CUCM to CME are not dialed and hardly I press 1 button my dial is declined with beep beep beep signal. It looks like no route pattern is configured.
Guys, could you please check my config.
Thank you.

The only thing I can think of is that you may want to try putting a CSS and PT on the stuff in CUCM. Make the CSS something that can call the PT, test, and let me know. An immediate beeping means it doesn't have a matching route pattern, but it should match since there are no CSSs and PTs. However, I would try that, just to be sure. Are there other route patterns in the system?

I noticed one thing when I was trying to add Route Group/Route List. I have SIP trunks for WAN and PSTN calls flow. However, on Route Group Configuration page I cannot see the trunks I created (pls see screenshots).

Why is it so and can it be the reason of my problems with PSTN and WAN call flows?

In the older versions of CUCM if you link a trunk directly to a Route Pattern it's taken out of the pool of available trunks when trying to add it to a Route Group. The general recommendation is to always use the Route List - Route Group construct.

Hi guys,

Thank you very much for following up my thread. The problem is resolved. Below is my working config, and I hope it will be helpful to someone else.

I just got a couple of questions so far:

1. As it was a lab environment the route to the subnet where CUCM resided was know to CUCME by means of routing protocol. In production environment the subnet with CUCM would be invisible from outside. At the same time, I suppose that in production environment CME sits behind firewall as well and not visible from outside. Which ports should be redirected/forwarded for SIP trunk?
2. Is it possible for the same task (to connect CUCM and CME directly) to use some other protocol like H.323 or MGCP (or some other protocol)?

Thank you.
