getting 503

1. Brekeke Product Name and Version:
Brekeke SIP Server 3.14.4.12
2. Java version:
Corretto 11.0.16.9.1
3. OS type and the version:
Server 2019 Standard
4. UA (phone), gateway or other hardware/software involved:
CUCM 12.5
5. Your problem:
When a Cisco Phone dials to Brekeke it appears to not reach server. While i am relatively new to Brekeke i can dial locally from a 3cx softphone to the room. I am connecting to a JERON 790 system with Jeron 790 software 7978M. I had Cisco double check MTP. I am unsure which side it potentially causing the 503 error. I do not see a call attempt in the Brekeke Logs. Nor what appears to be call coming from the cisco via wireshark. I am unsure where to continue to look. ANY help would be greatly apprecited

Have you looked at this Configuration Note?

Yes I have verified all on the JERON side as well as Brekeke. at this point i am never seeing an INVITE from cisco. i do not handle that side so i have sent off the Wireshark and information to Cisco people in hopes to get to the INVITE portion... TY

If there are no INVITE sent from the CISCO to the Brekeke, it will be an issue at Cisco's settings.

> at this point i am never seeing an INVITE from cisco.

Are there any packets other than SIP-INVITE?
