atcomsystems.ca/forum Forums VOIP Phones & IP PBX Cisco Telephones and Systems Cisco CME and MC3810 as a gateway

Ok, so iam just starting to learn some of the VoIP cisco stuff, I have set up a small lab system with a ISDN PRI emulator and old 3640 with CME on it and a MC3810 with a T1/PRI in it to use as a gateway.

I have the inbound calls coming into the 3810 and going back out H-323 to the CME ok. I can dial the 4 digit extension numbers and recieve calls.

I am now trying to figure out the dial-peers in the CME to send the calls out to the 3840.

Any one got some ideas ?

Most 3810s don't support VoIP just VoFR and VoHDLC. Normally when you want to send a dial peer to a voip gateway you use the command session target ipv4:192.168.222.1 pointing to the voip gateway. What code are you running on it? You can configure the FXO like this:

Hmm, the 3810 must be doing Voip or it would not be passing the calls from the 3810 down to the 3640 running CME.

As I said I need the 3640/CME to send via voip calls from it up to the 3810 and out the PRI.

The 3640 has no voiceports in it at all.
