Hi,
A client setup was working fine before on the same configuration. The issue on the SIP trunk and came a week ago. In Saudia Arabia there are different telecom companies like Zain, Mobily and STC. This issue is only on the STC network when dialing a mobile number from cisco phone.
Problem when a call is made to any STC mobile number. It gives busy and after 7,8 tries, it finally goes and connect. Dialing to any Mobily or Zain network have no issues.
Regarding below description is have attached debugs for Successful and Unsuccessful call logs and Gateway configuration
Call on Zain network 058XXXXXXX is successful
Call on STC network 055XXXXXXX is unsuccessful
Need help
Regards,
