Hello,

I'm having a strange issue with my FusionPBX (5.5) install.

When extension from domain A tries to dial to an extension on domain B, everything works as intended. I have is_local enabled so calls are not touching external profile.

However, when an extension on domain B tries to dial to domain A, there seems to be a 3-5 second delay, which is resulting in the users speaking over each other.

I'm not seeing this issue anywhere else with any of my other domains. Both domain A and B are using the exact same Snom IP phones.

I'm using G722 as the preferred codec on all phones, with matching ptimes of 20ms.

Any advice on how I can troubleshoot this?
