CME 7.0 One way Audio when calling between different types of phones

klohse · ‎07-24-2015

Hi everyone,

i have a CME 7.0 in a 2801 in my lab with some phones:

7960 with SIP

7925 with SCCP

FXS with VIC-2DID

Dialing and answering works between all of them, but audio works only between the same type, as soon as i call for example a SIP phone from a SCCP phone i have one way audio or no audio at all. All codecs are set to G.711ulaw. DSPs are installed.

Any idea ?

Any help is welcome...

Have a nice day.

please provide

sh run

sh logg

sh dsp all

it looks like u need

allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip

thanks for helping, i replied some outputs.

Here are some screenshots from the phones.

I also replaced the complete 2801 chassis and the PVDM, no change.

I thought about plugging a second PVDM, but to do that i need to unscrew the complete chassis out of the rack.

here is the new config, i could only enter 1 with max-sessions.

Result is the same, one way or zero way audio, between same protocol it works.

I believe the DSPs are good because FXS to FXS works too.

Hi,

Are SCCP phones and SIP phones on the same subnet?

Are you sure that the call is established? From SCCP or SIP phone, double press on the '?' button and share the details (especially TX/RX packets).

RTP stream for calls between phones registered with same CME will be direct between phones in case both are using same codec. CME won't be setting in the media path.

During an active call please share the following:

1. Calling/Called number

2. show voip rtp connect

3. show sccp conn

4. show call active voice brief

klohse · ‎07-26-2015

thanks for helping, here is the output you requested.

It looks like the SIP phone receives no packets and the SCCP phone does.

I deleted commands which are not interesting...

HA, problem solved.

I had to enable IP Routing and CEF, now it works fine without changing the rest of the config.

I love these Cisco machines ;-)

Thanks for all the help !

Mohammed al Baqari · ‎07-27-2015

Not sure why you disabled it in the first place !! CEF is a core component in any Cisco router. The entire magic of Cisco routing/switching is behind CEF.

klohse · ‎07-27-2015

It was disabled automatically when i disabled the IP routing.

I did "no ip routing" because the CME is "on a stick" and routing was not needed.

Also i wanted to see packets in the debugger, so fast switching must be off.

Documentation did not tell me that CEF must be enabled...
