Hi Jiang,

Be sure you record_route() also to calls forwarded to GW - add the record_route() before the forward(). Also don't forget to do loose_route() in your script for requests within the dialog.

Best regards, Marian

Hi,all

I have a record route problem:

sip client===>ser====>(pstn)gateway

invite: client---->ser---->gw ring and 200ok : gw--->ser--->client ack : client--------------->gw

I use forward command forward pstn call to gateway. if (uri=~"^sip:9817") { rewritehost("xxx.xxx.xxx.xxx"); forward(xxx.xxx.xxx.xxx,5060); break; }

There is no record-route field in the 200ok packet. So client forward to gw directly. But when sip client call each other ser insert record-route field. Can someone tell me how to config forward command with record-route supported?
