suggest me if there are better sevice providers.
I have had issues with termination on teliax. Callers tell me I sound
choppy to them. Teliax origination has no problems at all strangely
enough.
If you used SIP instead of IAX2 with Teliax you will have better
quality calls.
The 'choppy' sound occurs with IAX2 and not SIP at Teliax.
I can recommend Teliax, but use SIP.
But I _am_ using SIP. I tried all the various teliax gateways including
the beta test ones and had choppiness with all of them.
As I said before, teliax origination had no choppiness problems at all.
Only termination had issues.
I had no problems - termination or origination - with junction networks,
despite the fact they had 3x higher latency than teliax. JN is more
expensive than teliax though.
Also, I have talked to others who had similar choppiness problems with
teliax. So it's not just me.
For whatever its worth, the majority of teliax users I'm sure have had
at least some audio choppiness. Teliax is obviously aware of this since
they have spent a fair amount of time recently moving/enhancing their
implementations. It probably has nothing to due with iax vs sip other
then those around this list know that at least some changes/improvements
have been also occurring with the iax code.
One other consideration is that its obvious calls are handled in
different ways depending on the origination and termination points. In
other words, various npa-nxx calls are handed off to different wholesale
providers that can also be the source of call quality issues. (I've
identified some very specific npa's where this happens to be the case.)
There are a couple of other well known itsp's that don't have those
issues, and its highly likely their implementations in terms of
wholesale delivery sources are different.
Overall, I'd give teliax folks high marks for paying attention to
customer service and addressing issues, even though they are very
closed-mouth about service improvement plans, etc.
