I have a new installation with a new SIP trunk provider. It seems everything is working except transfer. sipx 4.4.
Incoming external come through SIP trunk to attendant Hit 1 to transfer to conference bridge When transfer starts, call is dropped. This works find when a-party is internal. The problem might be in the INVITE coming from the REFER : "SIP","Request: INVITE sip:194.6.238.85:5061, in-dialog" causing them to answer with a 200 OK with no Contact header which sipX does not like. Can anyone see from the attached pcap why this is happening -- *Sven Evensen, Operations Consultant* *OnRelay* Elizabeth House │ 39 York Road, London SE1 7NQ, UK │ +44 (0) 207 902 8123 │ mailto:[email protected] <[email protected]> │ www.onrelay.com This electronic message transmission contains information from OnRelay, Ltd., that may be confidential or privileged.
