My question is: I have VoIP GSM Gate (2 gsm channels). He can work with my Cisco CallManager 6 by SIP.
I add two sip trunks with identical destination and different ports (5060 and 5061).
Also i add the test mobile destination and it works fine separately with each sip-trunks.
But when i created the route group and the route list (based on this sip-trunks) and make one call - it ok, but on the second parallel call i receive a busy ton.
Please prompt me, how can i make the calls by CallManager and GSM Gate with two sip-trunks (one ip address, two ports)?
Can u attach CCM detailed trace,
not sure if the destination is returning busy here message and ccm is not routing, you can check stop routing flags in CallManager Service Parameters.
