That’s becuase both of those companies send calls from multiple IPs. Chan_SIP can support a single IP which means you would need a trunk for each IP using Chan_SIP. If you converted to Chan_PJSIP for the trunk, you could add all the IPs to one trunk.
This would solve your issue and allow you to turn off anonymous callers.
Good points. I forgot to mention that I do have a more “traditional” SIP number for E911. I plan to transition that number to one of their consumer plans (which do provide E911 service) as soon as my prepaid commitment expires, but it’s a very important consideration and I was remiss to ignore it.
However, in my mind other than the E911 issue AD is very useful for small systems in particular. I’m moving towards a “digital nomad” existence, and the ability to spin up low-cost local/international numbers while maintaining direct US dialing/reception for business and personal use, all for a pittance, is a huge win. But as always, everybody’s use case is different and their needs will determine what solutions are good/bad/indifferent for them. For me, it means I can run a full VOIP PBX with 3 dial-ins for around $7-8/month all-in (including hosting costs), depending on usage.
Interesting news about being able to bump the channel count, too. I doubt I’ll ever need it, but I’m sure there are some who would benefit. Thanks for the info!
I don’t have any stats but here is my experience:
We manage dozens of systems, clouded and on premise and, at least once or twice every week, VOIP.ms tunks go down for a few seconds on all of them at the same time. The Montreal servers seem really unreliable. It’s been better since we switchted to Toronto, but we still have some issues. Not a major problem because is last only a few seconds, but still annoying. We had to switch from VOIP.ms to another provider for our bigger customers who couldn’t live with these frequent outages. Maybe it’s better in your area.
