Route Pattern (based on two SIP trunks with one destination)

[volkovvalery]

Hello!

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.

create a second non secure sip profile with another incoming port number and difined it to one of your trunks so each trunk has its one non secure sip profile and try again.
