[Asterisk-Users] Confused !

Sun May 14 07:09:04 MST 2006

1. In the extension definition, insert canreinvite=yes for each of your 
clients.
2. In the trunk definition, insert canreinvite=yes

Read about reinvite at 
http://www.voip-info.org/wiki/view/Asterisk+sip+canreinvite
Apparently some hardware does not like it, and obviously, both the client 
and the service provider with have to be able to use the same codec (for 
them to be able to talk to each other) but better if Asterisk is restricted 
to that codec on both sides to start with.

Please understand, I am trying to help and I don't know which parts (of what 
I'm saying) are not entirely accurate but normally if I say something wrong 
there are enough people who clamour to correct me.
