Inbound Calls fail PSTN Gateway

[Claudio Quiroz Cabello]

Hello Friends,

I´m working with CUCM 6.1 and route pattern and calls to PSTN. I´m receiving and sending 4 digits from PSTN at MGCP Gw.

MGCP Gw -> PSTN (4digits)      OK

Phones -> Phones (4 digits)      OK

PSTN -> MGCP Gw (4 digits)     NOK

CSS   OK

Partitions    OK

0.2[^1]XXXXXX          part_local_Chicureo (look m3 file)

Any another idea?

[Claudio Quiroz Cabello]

Carlo,

The CSS is 4 digits,

The similars routern pattern are in diferent partitions, please look the files: m1, m2, m3 y m4.

For local numbers try with subscriber format.

This box has been up for a year. Have considered rebooting before troubleshooting further this issue.

It could save you time and energy .

Please rate helpful answers!

Hello,

Is it just happening for the single number "5253" or for all number.

I see you have two E1, is the other one acting as a backup for inbound and outbound calls.

If so, can you shut the E1 0/0/0 and see how the calls are working on other controller.

From my understanding it seems like call manager is not responding with CRCX after the Gateway NTFY about the inbound event. Can you try negate mgcp with "no mgcp" and add mgcp back and test the calls.

It would be great if you can pull the detailed CUCM trace and attach here.

Thanks,

Kasi

Hi Claudio,

This time your gateway resonded and your gateway is sending different release code "Destination out of Order" to the PSTN.

Have you done any kind of modification?

Also please share the detailed RTMT trace of CUCM as well.

Thanks & Regards,

Nishant Savalia
