SIP Trunking Service Providers - UK 1

[EddieV3]

Hi,

I work for a company where I maintain multiple 3300 servers across a large network.

We're looking to SIP for our outgoing trunks (not my decision), but I need a list of Mitel approved/compatible SIP Trunking Service Providers for the UK. The latest one I have is from 2009. Is there a newer list available? Or can anyone recommend any? We support 2000 users, so the SIP trunks need to be reliable!

Thanks

Mitel Online, knowledgbase. Doc called SIP COE document
It wont tell you where the SP's are but it does tell you who is interop tested

We have SIP provided by Gamma.
As far as I know they are the largest supplier of SIP services in the UK.

They were very helpful when we were initially implementing the solution. Had a few problems configuring our Juniper firewall but we got there in the end.
Tech support guys were great, calls answered straight away - no long auto attendants or annoying music on hold.

We have had 1 failure in 2 years and this was rectified within 15mins.

I would recommend them

we support several UK Mitels, some using Gamma (without issue) the majority using

(we use them for all our inbound/outbound calls) and would recommend them (tell them Converged referred you please)

A control panel allows you to control which IP address incoming calls are delivered to etc

we'd be happy to help with any issues

I believe Gamma have two styles of setup, one that is authenticated by the IP address you connect from, and one which is authenticated by a SIP username/password. SureVoIP authenticate by SIP username/password.

thanks, Neil
