AS5400 configuration question

Unanswered Question
Dec 10th, 2008

We have an AS5400XM that we are testing for deployment. One of the scenarios we are testing is to use a SIP phone registered to an asterik PBX which then sends/receives calls to/from the outside world through the AS5400. We have had success with dialing in, but are having an issue with dialing out. When we dial a local number, we get a standard busy signal. When we dial a long distance number we get a fast busy. We're not sure where the problem lies.

The following is an example of the output from dialing a local number (debugging isdn q931 and dial peer information):

We're not sure if this is an issue with our configuration or if it is an issue down the line at the telco or something else. Any help would be greatly appreciated.

I have this problem too.

apparently telco does not recognize or does not know how to route that number:

Called Party Number i = 0x80, '3875116'

Plan:Unknown, Type:Unknown

984806: Dec 10 21:53:48: ISDN Se7/0:1:23 Q931: RX <- PROGRESS pd = 8 callref = 0x80C6

Cause i = 0x8381 - Unallocated/unassigned number

is that what your telco is expecting for calling party number IE parameters???

Hi Greg,

This table can be used to check cause values :).

http://www.cisco.com/en/US/docs/ios/11_3/debug/command/reference/disdn.html#wp1532

For example:

Unallocated (unassigned) number: The ISDN number was sent to the switch in the correct format; however, the number is not assigned to any destination equipment.

Just a comment, a couple of months ago, I had the following problem:

Resources unavailable, unspecified: The requested channel or service is unavailable for an unknown reason. This might be a temporary problem (here the only workaround was reloading the router :S).

Hope this info help you for future reference.

Best regards,

- Adrián.

Thanks for the help. I seem to be getting closer to solving this. I am now able to get a call through using call simulation from the AS5400, however still get the "Unallocated (unassigned) number..." error in the Q931 debug information. Is this a possible configuration issue or should I be looking somewhere else?

Thanks again for all the help.

g.hammond, I am trying to do the same thing using my AS5400 that you were doing. I was just wondering if you were able to get it working properly, and if so, would you be willing to share your configs on the AS5400 and the Asterisk side.

If so, please let me know. You can reach me here: psands @ phoenixdatacorporation .com

Thanks in advance.
