Using 4.0.1 >I assume you have already applied >http://track.sipfoundry.org/secure/attachment/20698/patch7.zip I did not have the patch applied. I have now applied it but I now get an even stranger behavior. Now a call comes in, when it goes to transfer, the call does not drop nor does it ring the phone. The call trace shows the last seq of events is Refer to SipXproxy and then a 407 Proxy Authorization Required, then another Refer to SipXproxy with a response of 407 Proxy Authorization Required. I let the call sit for a good 30 seconds and after those two Refer/407 cycles the call goes nowhere, I do not see any invites or packets actually being sent to the destination phone extension or a refer back out to Bandtel. -M _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/ I had this issue with bandtel. I was using an ingate with them. The issue I recall was the ORDER in which the SDP was sent, and i finally left them and went to Bandwidth.com where I had no issues with that. I didn't have a rosy experience with them (200 support emails in under 12 months).
