i implemented a SIP-Trunk (CM 6.x) with my telephony-provider. now i'm experiencing some confusing problems with CFA. An internal phone dials an internal extension with a configured CFA to an external number. but on the external device, i can only see the internal extension of the calling party. The problem is, the "Remote-Party-ID" ("from") in an "SIP INVITE" contains only the internal extension (can see this in the cm trace file). i can resolve this problem only while using the external phone number mask and "Last Redirect Number (External)" in the SIP-TRUNK configuration. So, it is important for me, to resolve this issue without using the external phone number mask! I've tried a transformation of the calling party in the desired Route Pattern - but without success. Can anyone help?
