[SIPForum-discussion] Transport switch witin a call.

[Samir Patni]

Hi All, 

 

Can a call contain both TCP and UDP messages. 

 

>From section 18.1.1 from rfc 3261 

"If a request is within 200 bytes of the path MTU, or if it is larger
than 1300 bytes and the path MTU is unknown, the request MUST be sent
using an RFC 2914 [43] congestion controlled transport protocol, such

as TCP."

 

Consider a scenario in which Invite is sent over UDP and for some other
subsequent request (say  A).

 Within the same call the Request length is more then 1300 bytes. Should
this request A be sent over 

TCP? 

 

Thanks, 

Samir Patni
