UC540 multiSite and transcoding

[John Martin]

Hi everybody,

I have a multisite configuration with two UC540. All works fine but there is something that it isn't work properly.

Scenario:    SIte A (81...)<-------------------------------------------> Site B (82...)

Calls between sites, no issue.

Call to a blast group from internal phone, no issue.

Call from SIP Trunk to a differents phones ( site A and B telephones ) ..... don't work properly. The Sip trunk is configurate in site B.

When a incoming call is in progress, phones in the site A and B ring. If somebody pick up the call from Site A, works fine. If somebody pick up the call from Site B, no audio.

I assume that is a issue with the codecs but I'm not sure how to fix it.

Any advice ?

2 active calls found

This is the voice call status while the call is active. Here , I make mayself one question.

1.- Why the call hasn't codec ? The extension 250 is a share extension.
