hi there
i have some problems with setting up a BT voip trunk. The issue here is I can receive calls and make outside calls, but only on landline numbers?
my setting:
- Provider: Generic SIP Provider
- Description: bt
- Proxy: bmnhb-03.bt.com
- Registration: check (peer-to-peer SIP trunk, no registration)
- Outbound Proxy: www.bbvservice-560346.bt.com
- Call Capacity: 4
- Prefix # w/"+44" : Uncheck (uses UK national numbering plan)
- Company Name: <Your company name> (this will appear as the Display Name field on SIP messaging)
- Account ID: 056xxxxxxxx
- SIP domain name: <blank>
- Authentication ID: 056xxxxxxxx
- Password: password
- SRV Recorded Lookup: unchecked if checked -connection failed
- SRV Auto Prefix: unchecked if checked -connection failed
- NAT Mapping: Uncheck (ITSP provides SBC/Outbound proxy)
Systemwide parameters
- Codec: G711u
- Outbound FAX: PassThrough
Can you advise - what needs to be changed?
2nd question - is regarding the FAX line which is using one of the sip numbers. Fax is on a fsx port, an extra user is created and the fax as an fsx devise is assigned to the user. In section inbound calls, sip fax number is routed to the fax user but unfortunately this setting is not working
Can I force the analog fax to send and received data via sip trunk? or should I use one of the fxo line and direct to fxs port?
thanks for any suggestions.
