I have a problem when i have asterisk connected to voxtream parlay i60 PRA port. When call is received to asterisk and forwarded to SIP IP gsm gateway call is always disconnected with cause 102. # 102 Recovery on timer expiry This cause indicates that a procedure has been initiated by the expiry of a timer in association with ETS 300 102-1 error handling procedures. Call is not disconnected if user answers the call in this 18 seconds. I think the problem is that all messages from ip gateway don't get forwardet to PRI channel and call is disconnected. What can be done to solve this problem greetings mk
