Hi Jorge!

I think there are two problems:

1. ser does not cancel the transaction weird - can you send your config?

2. A does not send an ACK in respond to the 408 A must not send the ACK after the 200 OK, but it must send an ACK after the 408. Looks like a broken client. Which client is it?

regards, klaus

Hello,

I was testing ser-0.9.0 in a scenario with two ip phones. When I disconnect one of them from the network, and the other phone call to the disconnected one and then cancel the call before the timeout happens, the following packets are sent:

A SER B (disconnected from the network)

 INVITE->
 <-100   
	INVITE->
	INVITE->

CANCEL->
<-200
ACK->

<-408 <-408 <-408 <-408 <-408 <-408 <-408 <-408 <-408

I'm using t_relay to route the INVITEs.

Thank in advance!!
