In order to change the attribute in the SDP, you need manually to alter the
SDP (at least for 1.5.x). Tha NAT-Helper module will not do this for you.
Please see the Textops-Module on how to do this.

hello,

 

I use  kamailio 1.5.4  with rtpproxy 1.2.1 

 

I try to change the ptime (RTP packet size) with the Nathelper module .

 

to do it I call the function rtpproxy_offer with the option "z20"  but the
"a=ptime:30" in SDP is not changed  

 

any idea ?

 

Regards

 

Laurent
