Even now, that peak rate is quite expensive for retail. Then again, they've probably got customers paying it, so that's a nice healthy margin :) As for the rest of my points, wasn't aimed at you personally Cal - more to the thread in general. The point still stands though that there's no wrong or right solution, it all depends on the requirements. Cheers, Alex

gateways testing DNS SRV records
by Karl Schmidt 29 Oct '13

29 Oct '13

I'm trying to figure out a way to see if a freeswitch gateway respects SRV records. I've been trying different sofia commands without finding the IP that it is using. sofia_dig returns just the A records. To be clear - let's say you are using example.com as your DID and have a gateway set up. The provider should have SRV records so that there can be graceful failures. To see the IPs to use - do dig SRV _sip._upd.example.com So my precise question is how to see the IP freeswitch is using for a gateway. (I'm assuming that freeswitch knows how to use SRV records?) -------------------------------------------------------------------------------- Karl Schmidt EMail Karl(a)xtronics.com Transtronics, Inc.

Re: [Freeswitch-users] UK SIP Trunk providers

I don't often post on this list (which is why I'm replying to the digest - apologies if we've moved on since then), but I just wanted to comment on a few things in this thread. @Richard - when you talk about SIP trunks, it's probably best if you clarify whether you're looking for a 'retail' solution e.g. something you can use yourself in an office environment for a PBX, FS box, etc or resell to clients that want to do the same) or wholesale - whereby you're going to be aggregating traffic from multiple customers via SIP trunks, hosted PBX, etc etc. There'll be a few differences both technically and commercially between these two offerings - e.g. most wholesale providers will only deliver inbound traffic to a SIP URI, and will more often than not expect traffic to originate from one or more static IP addresses. @Cal not sure what AQL ratecard you're looking at that charges 26ppm for UK Mobile Orange, I'd hazard a guess you need to divide that by 10? Even when you do that's still a little on the expensive side for wholesale. Wholesale providers charge minimums as they are, as the name suggests, wholesale. They are high volume low margin operations, and often don't sell 'retail' services direct to the public - e.g. Magrathea, Simwood - and will (last time I checked) require you to sign a declaration that you qualify to be a wholesale customer. Gamma, BT, Kingston etc obviously do have retail offerings but also have separate wholesale divisions. Gamma and BT (and I'd imagine Kingston too) will also provide you retail services that you can white label and sell on to your customers under your own brand - no equipment required. Companies like Gradwell, AQL (who jointly own a third party called Telephony Services, who you might have come across), SureVoip, SipGate are (in my humblest opinion) retail providers. They may also have white label offerings like the above. Now... if after all that you fit into the wholesale customer category, you might want to split your requirements into UK and international, and again split inbound (numbering) from outbound. Why? Because as (I believe) Andrew said, there's no one service that'll meet all your needs. Example: Voxbone will happily provide you numbers in umpteen countries, but you'll find that they're i) expensive for UK numbering (actually they're expensive full stop, but that's just my personal opinion), ii) there is a minimum spend, and iii) they won't help you much with your outbound requirements (except for 999/112/911 etc traffic in a few countries). Likewise, Magrathea and Simwood wouldn't be a bad choice for UK numbers, but if you want numbering in the US, Australia, etc, they're probably not going to be able to help. As for BT IP Exchange, let's leave that discussion for another day, but suffice to say it's not a regulated interconnect product - so comparing a provider who hosts their numbering on BT IPX with one that leverages TDM connectivity to BT is like comparing apples to oranges both technically and commercially. I'm not going to tag on a plug for my company to this thread as it'd be bad etiquette - but ping me a mail off-list if you want to chat further.

Best practices for parallel fork with redirect on one branch
by DanB 29 Oct '13

29 Oct '13

Hey Guys, Have met a situation where I need to do parallel call forking with bridge application and on one of the legs will receive a 302 which could mean another parallel fork there. Have tested the following scenarios: 1. Sip profile with manual-redirect=true. Here I fork the call using bridge with "," as separator and parallel fork works. The issue is that as soon as one of my forked legs receives 302, the other will be cancelled also and 302 will be handled further in it's context. Is this the expected behaviour from bridge? Question here: should it drop one branch of the parallel fork if other is receiving redirect? 2. Sip profile with manual-redirect=false, leaving mod_sofia doing the handling of the redirect. After I fork the call here with bridge, only the leg which receives 302 will be redirected which is the expected behaviour by me. The issue I have here is that I do not know how to influence mod_sofia to handle parallel forking out of 302 and not very obvious out of the documentation I have digged so far (I receive 2 contacts in redirect btw which I would like to fork also here). Question here: may I specify the type of fork mod_sofia should do in some way? Thanks in advance for any tip! DanB PS: Logs available at request if needed.
