[OpenSER-Devel] TM-API-Calls: t_request, Presence and others....

[Carsten Bock]

Hi Klaus,

if i understand the t_request-method right, i give it the following
parameters:
- m: Method-Name 
- ruri: Request-URI
- to: To-Line
- from: From-Line
- h: Additional Headers (if any)
- b: Body (if any)
- c / cp: Callback + Parameters

I want to send a request to a specific phone, e.g. a Request to 
"sip:user at 192.168.1.1:2054;line=c5rotyx7"; if i put this in the
To-Parameter, it'll only be in the "To"-Line, not in the Request-URI...
And even if i could put it there, that would not affect the
t_request-Calls from other modules like the presence modules.

Carsten
