Hi Bogdan,

Thank you very much, so this doesn’t have any impact on why the call being transferred are dropped ?

I am trying to transfer a call using the refer method as that is what the cisco phones use.

The network is setup like so opensips proxy à asterisk gateway à carrier


Inbound call comes into the phone like so: carrier à ast à proxy à phone A

Phone A needs to transfer call to phone B: Phone A dials phone B à phone B picks up à phone A presses xfer button and call is dropped.

Any help would be appreciated.

Hi Brian,

That warning means OpenSIPS found a Route header (while doing loose_route) that is suppose to be of its own, but the network information from the header does not match any of the OpenSIPS SIP listeners.

Best regards,
