Hi All
I am having some real issues with a BT Business VOIP account in the UK. (with an 05 number?)
BT in the documentation say it is modified SIP and should work on any phone system.
Even though the trunk is registered i can not make an incoming or outgoing call on the trunk at all.
Has anybody in the forums got 3cx to work with BT VOIP?
In the past when i have had a trunk register and i cant call from it i have had to change the outgoing CLI to start 441210004444 instead of 01210004444. When i take the 0 away from the BT 056 number the trunk fails to register at all.
I'm using 3CX V12 on Win7 Pro
Domain: bmnhb-03.bt.com
Alt Domain: sip.bbvservice.nat.bt.com
Any help would be much appreciated as Bt just don't want to know and only support trunks on BT kit. (standard)
Thanks
Richard
