Hey all, first post so excuse any omitted detail!
Our Asterisk box at site A is connected to another at site B via IAX2 trunk (no site-to-site link involved - it just routes over the internet). Site A doesn’t have a direct connection to the PSTN, but site B does, hence the trunk. This is an interim measure for us until we can get a trunk to a third party provider with a PSTN gateway so we don’t keep having to use site B’s (which isn’t possible long-term).
On a side note here: any suggestions for SIP/IAX2 trunk providers in the UK? I’ve so far heard of Gradwell, Callsure, Adepteo, and AQL - anyone with experience of any of these?
Anyway back to my original question. Inbound call routing is:
- Call to one of our public numbers
- Arrives at PSTN gateway at Site B
- Site B sends to a custom destination which is actually an internal extension or ring group on the PBX at site A (didn’t get chance to play with DUNDi to do this properly)
- Call is answered at Site A
This works fine, but I can’t see a way to set alert info on this route to what I need to make my phones ring properly. The inbound routes at Site B set alert info properly, but it’s like it doesn’t make its way down the IAX trunk to Site A. The trunk config has set
context=from-internal
Could that be part of the issue?
Thanks in advance to anyone who can point me in the right direction.
