Hello,

i have a problem with a Sip trunk to a SAP-BCM PBX.

In and Outbound Calls works fine but when the SAP tries to transfer an
inbound call to an outbound call there is no-way-audio. Two outbound
calls could be transfered without any Problem.

In the sip trace i see that the SAP BCM make something wrong with the
Reinvite. (wrong SDP IP and Ports information, and only one reInvite
package for the inbound call, nothing for the second)

My Question is if there is someone who has a working trunk with a SAP
BCM PBX and if they had the same problems.

I?ve used Asterisk 1.2.35, 1.6.1.11 and also 1.6.2.rc8 but on every
version it doenst work.

Best regards

Steve Smith
