Hello,
I'm experiencing the following problem:
I have this scenario: PSTN - SIP GW - CUCM6.1 - SIP TRUNK - CUM8.6
Phone A (extension 33476761834) is registered on CUCM8.6, with external forwarding to the PSTN.
If someone from CUCM8.6 calls - it works.
If someone from CUCM6.1 or from PSTN calls - fast busy. Error in CUCM traces:
