[OpenSBC] Calling inbound issue

Hi All

I hope you can help with this very weird issue I am having!

I have a path set up like so:

PSTN -> Asterisk -> OpenSBC -> OpenSER -> SIP Phones

SIP Phones register to the OpenSER server.

Calling from the PSTN to an Alias on openser rings the correct SIP
Phone, however when it is picked up, the caller on the PSTN gets
connected back to themself!

Calling from a SIP phone to a destination on the PSTN works fine.

Any ideas?

Regards

Dan

I don't quite get it. What do you mean by "gets connected back to
themself!" ??? The PSTN caller hears himself as an echo? The callee
hears nothing? If you could provide a packet capture from the SIP Phone
side, perhaps we can tell what caused this quite hilarious behavior.

Thats exactly it! The caller simply gets himself as an echo and the SIP
phone displays "Call Ended" and hangs up.

I will be able to get a packet trace later today when back in the
office.

Cheers
