Hello, this is my problem: I would like to use Freeswitch as a gateway between our Hipath PBX and an external SIP provider. For that I created a Hipath SIP account that is working (tested with X-lite). Now I would like to let Freeswitch act as a client using this SIP account. Whenever there is an incoming call Freeswitch should act on it and forward this call to an external SIP provider. Is this possible? Does that make sense? Are there alternatives? At the moment I'm stuck to configure Freeswitch as a client. I added the Hipath SIP account as a gateway. When I compare the SIP traffic of X-lite and Freeswitch using Wireshark I found out that Freeswitch dows not offer the 'Subscribe' option. Is this the reason why it fails? Can you help me? Thanks in advance. Dieter
