So we have some VoIP numbers with BT which we got because we moved office. We had our numbers ported to VoIP with BT and then redirected to the new pstn lines as to keep our number.
Now that we have moved office we have put in a VoIP phone system Kerio Operator in the instance. The phone system is working and we have tested it with a VoIP number (not a BT one). Now we want to add our number to Kerio Operator.
We have been provided the following information from BT:
Number/username: 0560*******
SIP password: OURPASSWORD
Domain: bmnhb-03.bt.com
Alt Domain: sip.bbvservice.nat.bt.com
Outbound proxy: www.bbvservice-560349.bt.com
So trying to use the above details fail. In Kerio Operator I have the following options:
Hostname or IP Address
Proxy inbound & outbound
Port Number
Username
Password
For the Hostname or IP address I have tried the the BT supplied Domain - bmnhb-03.bt.com as well as the alt Domain - sip.bbvservice.nat.bt.com
I've set the outboud proxy as - www.bbvservice-560349.bt.com & left the inbound either blank & tried using the Domain - bmnhb-03.bt.com & sip.bbvservice.nat.bt.com
None of the combnations work. The problem seems to be in the first instance that the Domain & Alt Domain are not discvorable.
if I try an nslookup on bmnhb-03.bt.com & sip.bbvservice.nat.bt.com I get no response back from the network the phone system is on and from various other networks.
BT refuse to give me any further information that flat our won't help or are unable to. They won't put me through to anyone that can help either. So if anyone has any information on how to get this working that would be great.
We would simply move SIP providers, but unfortuanlly BT tied us into a three year contract at the time of our move and we where informed that the VoIP line would work with any VoIP product so now we are essentialy stuck with a service we can not use because they refuse to help or provided correct information.
