Multisite UC500

[sabbinanti]

I have two sites, one with a UC560 an another with a UC540. I manually created a VPN tunnle and setup dial peer. The two sites can use 4 digit dialing and have access to the PSTN from each site. Calls from IP Phone to IP Phone work just fine.

However, call forwarding to voicemail (NOAN or otherwise), access to the conference bridge or even dialing CUE directly from the site with the UC540 to the site with the UC560 fails as unknown number.

When calling from the site with the UC560 to the site with the UC540, this is not a problem.

Any help would be appreciated.

Thanks,

S.

Hello Sebastian,

Please try to use codec g711ulaw between sites under the dial peers.

HTH,

Hi Sebastion,

You either have a Codec Mismatch issue going on, or transcoding is not working properly.

If you do what Alex says, and it works properly in both directions, you can then further investigate using different codecs to reduce bandwidth, but for testing purposes putting everything on G-711uLaw is the best methodology in diagnosing the problem

Cheers,

Hello Sebastian,

This is set to deault codec which is G729 because it is not set under the dial peers.

So under :

dial-peer voice 2205 voip

dial-peer voice 2206 voip

dial-peer voice 2400 voip

you should include :

voice-class codec 1

or directly

codec g711ulaw

HTH,

Alex
