ISDN Calls - Bearer capability not implemented

[walter_vignolo]

Hi.

Many of the calls are established but only some of them are disconnected.

I have this log in the Cisco 2900

Do you have any aidea ?

Thanks..

Apply the following to your D-channel:

voice-port 0/0/0:23

bearer-cap Speech

!

Hi Cris, thanks for your feedback.

I tried with this command but the problem continue.

Regards.

[Chris Deren]

I've seen this caused by codec mismatch as well, could that be the issue here?

Chris

[walter_vignolo]

Hi Chirs.

We´ve tried change the codecs but we don´t have results.

Do you know a debug command in order to detect the codec mismatch ?

Thanks.

[Chris Deren]

To detect codec mismatch you would need to look at the voip protocol debugs, depending on protocol user it would be different commands, for SIP use "debug ccsip messages"

H323 - "debug h225" or "debug h245 asn1"

MGCP you would look at CCM SDI traces.

HTH,

Chris

Got to the bottom of this

For MGCP Gateways anyway .. 

On Call Manager - goto the gateway in question and drill into the Cisco MGCP T1 port config..

Scroll down and change the Channel IE Type from the default ..

USE Number when 1B OR Slotmap

TO the correct setting

Timeslot Number

PCM Type = u-law

thats for US T1 PRI

Hope that helps ..
