We are using SAP Contact Center 7.0.12 integrated with Asterisk 11.
Call is working appropriately but when the call is on hold, it’s dropped after 30 seconds.
When we executed a sniffer we note the following information:
X-Asterisk-HangupCause: Requested channel not available
And SAP Contact Center use Virtual Units like components.
When call start the SIP is using 192.168.26.3, when the call is on hold the communication is changed 192.168.26.6. I think Asterisk dropped call because it unknows the IP 192.168.26.6
Does someone know how we can solve the issue?
