Jun 17th, 2009

Hi, I want connect a E1 to a router 2851 with CUCME 4.1, but whenever I dial some DID (after configure the card VWIC2-2MFT-T1/E1), the calls are not routed to the extensions, the first thing the router do is give me a tone of reorder to dial the extension and then the call is routed to the extension

Noete you can group the analog ports under trunk group, that will allow you to collapse most DPs under a single one.

Do you have more than one Pots dial-peers configured?

If so ensure you have incoming called-number. & direct-inward-dial on the dial-peer you expect inbound calls to use.

Is the E1 to PBX up ? Check show controllers E1.

Is the PBX ready to receive 4 digits beginning with 16 ?

If yes to both questions, take "debug vpm signal" with "term mon" whe dialing 16xx.

altesan35 Mon, 06/22/2009 - 09:39

Sorry, I think not explain me good

When I try make a call to outside, the router give me dial tone, however if I dial any digit sequence, router only catch first digit and ignore the rest of digits

altesan35 Mon, 06/22/2009 - 13:38

One more time, s

orry, my english is not very well

I try connect the PBX (Panasonic 1232) to a router Cisco 2851 (with CCME 4.1) using card VWIC2-2MFT-T1/E1.

Incoming calls (Router to PBX) are completed succesful, but outgoing calls (PBX to Router) are not completed.

When I try make a call (from PBX), I hear dial tone and saw with the "show voice call summary" command that one line is goes off hook, then I start press digit, only the first digit is understand, the other digits are showed incorrectly (example 4#, or #) so the call is not complete.

What does you mean with check controllers, I don't understand???

I attach the debug file

This is ended

I configure the route of the calls to the interface appropriate. Thanks for your help
