AS5300 call to 827-4V:FXS

Hi All ...

I have a problem in the following scenario, and I hope you can help me:

PBX-A ------ AS5300 -----------------827-4V ------- PBX-B

.......isdn q-sig..................wan...................FXS

When I make a call from PBX-A to PBX-B, the 827-4V gives me a dial tone, instead of ringing the PBX-B. In this dial tone, if I dial anything, then I can hear the ring, and site B answers the phone call.

And when the PBX-B calls PBX-A, the call dials and rings OK on the site A.

The same happens when we change the 827-4V by a MC3810.

Thank you ...

Without seeing the config, my first guess is that on the pots dial-peer in the 827/mc3810 the digits are being stripped. The default behavior for pots dial-peers is to strip any explicitly matched digits.

for example:

if the 827 receives 4321 and your destination-pattern is 432. then we will strip the 432 and forward only the 1 to the PBX.

To eliminate this behavior, you can configure the following under the pots dial-peer:

- "no digit-strip" if available in your IOS


- "prefix xxxx" where xxxx matches the explicitly matched digits (432 in the case above).

Let me know if this doesn't work.

Hi Clay ...

It worked fine with the "no digit-strip".

Thank you very much for your help and attention.

Kanno ...
