Hi There
i have a mitel 3300icp setup with sip trunking
when a call is made or recieved via the sip trunk and answered on the mitel ip terminal and transfered to another ext, the call does not "connect" on the other side.
the calling party keeps hearing music and the transfered to party hears nothing. whe the transfered to patry hangs up the call disconnects on both sides.
i can call successfully between the exts.
when i transfer a call from an analogue line it works fine
when i do the same test using 3rd party sip phones or analogue phones it works fine.
whenever i use a mitel ip phone the call fails
please help, this is driving me insane and i cannot get it to work
