I recently set up a couple of remote extensions and I’ve been experiencing problems with them. My server is hosted elsewhere, so technically all of my extensions are remote, but these new ones have been especially troublesome, while at our main office the phones work perfectly.
I’m not currently posting any technical information because I’m not sure what is needed to diagnose this issue. I can update with logs or other technical information with guidance as to what I should post.
Here is what is happening:
I can make calls with these extensions, either to other extensions or to an unrelated phone, and the other party receives the call. They can answer, and they show as connected. But only sometimes does sound go through, mostly it does not. It seems rather hit and miss. There is a possibility that making a call after waiting a long time seems to have more success, but I’m not sure if this is the case. Also, sometimes after waiting for around 20-30 seconds, the call will “connect” again, and sound will go through. But again, this is not always the case. BLF info is coming through as well. And they are listed as OK in the astierisk infos peers section.
I have tried changing sip settings to nat = yes.
I’ve tried temporarily disabling iptables, even though our IPs are whitelisted here. (I’m using travelin man)
One thing that may be the problem is that we bounce between a couple of public IPs rather frequently. Could that be the problem?
I’m tripped up because this problem seems so hit and miss. Do you guys have any suggestions? I can post more information here if it is needed, but what I really need is another place to look for the problem.
Thanks so much.
