Sip Call failure

[Suchi]

Hello,

Below is my voice setup,

CUCM----CUBE---SIP Trunk---ITSP

I can make inbound & outbound calls without any issue except one external party. When I make a call to that particular number, end device rings & disconnect when other end user pick up the call. But incoming calls from this number is working fine.  When I check logs, it indicates codec issue.

CSeq: 102 BYE
Reason: Q.850;cause=47
Content-Length: 0

Do i need different config/dail peer for this number?

Thanks

Suchira
