Bearer capability not implemented

[Peter Valdes]

Hi,

We are currently getting transfer issue on our network. When received incoming call to our attendant console then we attempt transfer from AC to outside mobile via PRI, I get cause=65 from debug voice ccapi inout aswell going out the correct dial peer which is Outgoing Dial-peer=9000

Same result when using Cisco IP Phone, call receive then transfer to outside mobile via PRI.

Also, under the Device -> Gateway, when I check Media Termination Point Required the transfer works but takes down other service such as our Fax.

CUCM 7.1.5

H323 to Voice Gateway

E1 PRI

See attached running config and Q931 debug.

Help please.

My guess is that the carrier doesn't like the ANI you're sending here. You may be missing an External Phone Number Mask somewhere in CUCM.

Can't be, because CM is disconnecting, not CO:

I don't know much about CM but it may be short of media resources or something.

Nice catch Paolo; clearly it's time for sleep here.

We would need detailed-level SDI traces from CUCM to figure out why it tore this call down. If you collect them be sure to also give us the matching Q931 traces again so we have a shot at matching it up in the SDI logs.

Thanks guys for the reply.

This has been working since we completed upgrade to CUCM 7.1.5 last year. Problem started recently around a couple of weeks ago.

I will get the trace ready according to the link above and get TAC to have a look.

Thanks again guys.
