asterisk users - Jul 2006 - Canreinvite and remotely registered devices

We have a customer who would like to do RTP directly between SIP 
devices. The devices are not registered directly to Asterisk, but to SER 
on another machine.

It seems in this case "canreinvite = yes" is never used. Does anyone 
know of a way of persuading Asterisk to issue re-invites in this case?

What do you mean by not used? Even if going through SER it should still be used.

Although not clear from your posting I assume that the call between the
two phones is setup through the Asterisk server. Asterisk will not let
go if you have ie the "T" or "t" option in your Dial
statement. Remove
those for starters. If Asterisk is not involved at all I guess you need
to find out what the equivalent of "canreinvite=yes" is in SER
country.

Patrick

Patrick,

Yes, Asterisk is handling the call setup for billing purposes. There is 
no t or T in the dial.

SER does not have an equivalent of canreinvite as it is a SIP proxy not 
an end point.
