SIP to SIP extyensions on MBG/Mitel5000

[jchristman2002]

I have Ascom handsets registered to an MBG tht is connected to a Mitel 500.   The Ascom handsets are registered to the MBG and Mitel 5000 the remote Ascom can make calls out through the SIP trunk or call Ascom and 5330s at the main site.  They can also call 5330s at the remote site that are also connected as teleworkers.   But the Ascom handsets are the remote site cannot call other remote handsets and the 5330s at the remote site cannot call the remote Ascoms.  just get a call could not be completed on the 5330s and invalid number on the Ascoms.

jchristman2002,

Have you looked at packet captures yet to see what the problem is? It sounds like the Ascom phones are trying to do peer-to-peer and failing at it.

Thanks,
