How freepbx sets it is another question though I am not sure what would go wrong on a provider side as they usually standardise their systems. That said its always possible. Your error is a timeout in response to a line seize so either your provider isn't seeing the signal, they aren't replying for some reason or you aren't getting it back. That could fit with changes to the signalling channel. Ideally if you can look at the signalling you can see whats happening. I can't recall if asterisk will let you do that. CAS signalling is very simple in that its just reflecting what used to be a physical change for the line controls. Can you ask your providers to see what they see or reset the trunk when the issue comes up to see if it matters Good luck > On 08/03/22 11:54, Duncan Turnbull wrote: > > It’s been a r we hike since we used these cards.

Re: [asterisk-users] R2 error Seize Timeout
The provider is the timing source. Both wanpipe1.conf and system.conf have the timing sources set to the remote side: TE_CLOCK = NORMAL span=1,1,0,CAS,HDB3 I still have a feeling that the problem is on the providers side as during testing we never saw the issue. I have modified wanpipe1.conf to be CAS but the strange thing is that the freepbx gui does show CAS there but sets CCS on the configuration file. Now I have to wait and see if the problem persists.

Re: [asterisk-users] R2 error Seize Timeout
Hello, I must admit that I have never set up an asterisk system with R2 signalling. But from the config files point of view, you stated TE_SIG_MODE in wanpipe1.conf as ccs which should be cas, right ? If this does not help, you need to connect an external E1 Monitor.
