[OpenSIPS-Users] Call Spy in opensips

[Flavio Goncalves]

Hi Indiver,

There is another option but depends on the phone. Some phones support the
SIP "Join" header as defined in the rfc3911. There are some phones that
support it such as  Aastra and Atcom. I haven't checked Polycom and Linksys
but I think they support too.  Basically you will need to get the dialog
information from the call you want to barge-in. You can do it with the
dialog module, then you will need to call the phone you want to barge-in and
use OpenSIPS to include the join header with the proper dialog information,
Call-ID, To Tag, Form tag and Cseq. Read the RFC3911 for more details.

Best regards,

Flavio E. Goncalves
