SIP Traces-Trunk with ISP

[Khurram Tariq]

hi all

i have attached CCSIP messages with it 

call Flow: ISP SIP Trunk---------->CUBE-SIP Trunk---------->CUCM

i am new in SIP configuration with cube and Service Provider, First Issue: we have a DID complete number 364909XX and i have configured my ip communicator with 0998 DN ISP want complete number with 36490998 but from here we are sending only 0998 (our internal DN) help me to send complete number to ISP.

2-if you observe traces there is sip port number Via: SIP/2.0/UDP 221.120.192.34:5060;branch=z9hG4bK0C48;rport=50906 This sip port 50906 changed everytime but ISP only want sip port 5060 whohc i already configured in my CUBE GW and CUCM also

please let me know the solution of this issue.

1) have you configured your CIPC with external phone number mask 364909XX?

also make sure in Route Patter configuration you've checked the 'use external phone number mask' box.

You may also set 364909XX in the calling party transformation mask in the RP.

2) Also configure "connection-reuse" under sip-ua to change the remote port.
