I'm using pjsua python module, and I don't know how to create a custom message like below:
mY'0E@@b,%+&KEEPALIVE sip:user@192.168.0.10 SIP/2.0
Via: SIP/2.0/UDP 192.168.0.10;rport;branch=z9hG4bKPjgdQdo8azxxwRZ9aCVJy5Wdr27fTgDBUy

Contact: <sip:server@192.168.0.10>

Applier-ID: 24598

User-Agent: PU/1.0.0

Exists any way to do this? Thanks.
