Communication between asterisk internal numbers does not work. What to do?

Question

Asterisk

Good afternoon.
I'm with Asterisk deeply on YOU!!! Therefore, please do not swear.
The crux of the matter is this:
There is a playground. The Asterisk server is on. On it the sheaf with automatic telephone exchange of Panasonic is configured. All phones work through Panasonic. There are also phones registered with Asterisk. Within the same site, all these phones communicate well using internal numbers.
Now I am setting up phones on Asterisk for an office that is located on a different site.
When I call a phone that works through Panasonic on the extension number in office1, everything works fine. When I call from office 1 to office 2 from a phone that works through Panasonic. When I call from office1 to office2 from a phone that works through Asterisk, everything works fine.
I don't understand what's the matter. Tell me where to dig?
Here are the Asterisk logs when calling from office1 to office2 from a phone that works through Panasonic:

Answer 1

According to this log, everything is working fine. Both channels enter the bridge, then leave it 21 seconds later, with the Panasonic channel exiting first.

Answer 2

It is very similar to the standard limitation of talking in Panasonic - turn off
