Hi.
I installed Openfire 3.7.0 (on debian sqeeze) + Spark 2.6.3 (on W7) and I'm trying to test the Spark's SIP plugin with my Asterisk.
The phone plugin sucessfully logins in to my Asterisk.
When I try to make a call the line is established, i can hear the other side for a second or two, but then it start to play a 1/2 second loop of past sound over conversation which won't stop even when a drop the call and continues to play until I close the Spark.
I tried with different codecs (ulaw, alaw, gsm...), network configuration (asterisk on same subnet, different subnet, behind NAT), even odler builds of Spark with no luck.
Asterisk works OK with other clients.
Did anyone else encounter this problem?
