We have established a SIP trunk between Nortel PBX and CUCM as below,
IP level connectivity between Nortel and CUCM and vice versa is fine.
We are able to ping each other.
But we are unable to make calls between the 2 systems
Nortel uses g729 codec and CUCM using g711

Nortel PBX —>SIP Trunk—>CUCM

Please help to sort this problem

To complete this design you would also want to have a design for an internal dial plan which would include Lync to CUCM and CUCM to Lync calls. Any thoughts on using this model to have the dial plan in AD (vs having to build the dial plan in CUCM and in Lync)?

This is great that you published this.

In addition to sending the call to Lync, I would want it to then be sent (redirected / diverted / late fork) to Cisco Voice mail in case of a 4xx/5xx SIP message, or a certain timeout while RINGING/TRYING the Lync client. How would you do this? What would such a setup look like?

I am using CUCM 8.0.1
MTP Required is selected
G729b is chosen as the default codec, in the sip trunk settings.
My service provider claims that they receive NO SDP from us on invite to the CUBE.
Is there another option that I have to select in my SIP profile or the SIP trunk config in order to get SDP to send?

We upgraded our 4500 last night. Do you know how far back the history is allowed to go on the call details? Trying to find a setting for this and have been unsuccessful.

1. Slow response, even with no applications configured, if you are a fast dialer you will suffer with it.
2. The latest 9.3(2) firmware have a horrible bug, randomly i will stop responding to the keys pressed unless you lift the handset, speaker phone dialing won’t work .. you will have to revert to the 9.2(1) to sort this.
3. Call pickup and lots of what you can call basic features won’t work between SCCP and SIP phones, even from SIP to SIP if you are running CME as softkeys template is not applicable.
4. Basically if you are CME based .. avoid it
5. The gloss finish of the top gets smudgy easily.

I hope some of these issues will be fixed with the CME 9.5 and the new phone firmware.

$screen /dev/tty.usbserial 9600

What brand of USB-to-Serial adapter are you using?

However, when I connect to the router via the screen command all I see is a blank screen and the cursor moves all over the place; but no text is displayed. Also on mine it just shows /dev/tty.usbserial there is no numbers or indication that it sees the specific model of my converter. Can anyone help me? I would be ever so grateful. I opened a case with apple care but they were unable to resolve the issue for me.
