[OpenSER-Users] T38 re invite not being sent to VoIP provider

[Jesus Rodriguez]

Hi Mike,


> Does anyone have any idea where I should start to find this problem ?


Looking at your configuration, seems that both INVITEs and re-INVITEs  
go to route(ROUTE_AUTHTEST) ... after that, who knows :)

Add some xlog() logs to your script and try to find what occurs with  
the re-INVITE.

Also, obtain a trace of the signaling with "ngrep -Wbyline -d any - 
qt . port 5060" (or whatever port you use) and send it to the list.

Regards.
