I've two uc549 connected over an internet vpn between a H3232 trunk.
The UC540A is in italy and have two ISDN BRI The extension are 10x, 11x and 12x
The UC540 Bis in switzerland and have also two isdn bri the extensions are 16x.
The user (for example) 101 in italy call 160 in switzerland. the user 160 put the call onHold and then call an external number. Whern the external number is online the user divert the call to 101 but the call goes down.
From switzerland to italy all works well
can you have any suggestion?

Hi,
good to hear that, I think you need to add h323 voip interface and h323 voip bind srcaddr xxx.xxx.xxx.xxx for the voice interfaces in both sites. after that the H323 dial-peers will work

Hi,
it seems it is related to codec issue. I assume that the codec over WAN between Italy and Swiss is g729. the call to BRI is g711ulaw. when you transfer the call it drops due to codec mismatch.
you need to create transcoder in Swiss UC540 to solve your issue.

Hi Anas, manye thanks for help.
The codec was correct, and I've solved the problem configuring the trunks between callmanagers in SIP instead of H£23.
With SIP now all works well.
Thanks for help
