Hello Rosario,
Tha ACK contains a branch id = 0 in the first Via: field. I can
imagine that some implementations are not happy with that.
Via: SIP/2.0/UDP 19x.6x.19x.4x;branch=0
When you're compliant with RFC3261 this branch id. should start with
"z9hG4bK". The branch id. is used to detect loops.
Best regards,
Jan
