hello,
we should connect a LYNC-Server with a SIP-Provider. Therefore we use a Cisco CUBE 2951.(15.2.3T)
Calls outbound (From LYNC to SIP/PSTN) are ok
Calls inbound (From SIP/PSTN to LYNC) are ok
Calls Forwarded back to SIP/PSTN are not ok (The call is successfull, that means signaling, rtp is ok,
but the siganlling numbers in sip-header are not ok)
Detail:
The provider complains : Wrong A-number and no Diversion Header
FROM should contain the number of the forwarder or a Diversion header must be added.
example :
A: +4989-111111 (SIP/PSTN)
B:+49711-123456 (LYNC)
C: +4989-222222 (SIP/PSTN)
B has a Call Forward all to C;
A calls B - B forwards the call to C
The call outgoing contains in the FROM-field <sip:+4989111111@....>
Any tips for configuriation the CUBE (especially with LYNC) ?
regards
