Hello,
I am attempting to use sipx as a solution for a small business telephone
system. I have 10 Polycom IP330's and one Polycom IP650.
I would like to have the following configuration:
- Firewall (either m0n0wall or PFSense) on a DSL circuit
- SIP Trunk using sipxbridge
- Support the following
- Single Incoming number rings all handsets
- Blind and consultative transfers
- Hold (preferably with MOH)
- MWI
- Buddy Lists
- Conferencing
I have incoming and outgoing calls working successfully but whenever I
attempt to transfer a call or place somebody on hold the call disconnects.
I am assuming that I am having either a NAT problem or a configuration error
in the phone group / or line configuration. I have played around with both
a hunt group and a shared line configuration as a solution for ringing all
the incoming phones at the same time and encounter call hold and transfer
issues with both setups.
Here is an overview of the current setup:
Dedicated DSL Circuit (Connection tested at
http://myvoipspeed.visualware.com/ MOS score of 4.0 with .4ms jitter and 0%
packet loss)
Firewall m0n0wall
Inbound NAT and Firewall Rules
- TCP/UDP 5800 from WAN IP to sipx internal IP
- TCP/UDP 30000 - 31000 from WAN IP to sipx internal IP
Sipx from installer CD 4.0.1
- Single server running park running SIP Trunking, Conferencing,
Management, Primary SIP Router, and Voicemail Server Roles
- Followed directions here
http://sipx-wiki.calivia.com/index.php/SipXbridge_Overview_and_Configuration
(multiple times)
- Sipx is not the DNS server but the DNS configuration test
completes just fine
- Sipx is the DHCP server
- Sipx is managing the phones
Polycom Phones
Bootrom: 4.1.3 release
Firmware: 3.1.3RevC
Any help would be greatly appreciated and upon a reliable working setup I'd
be glad to publish a very specific tutorial fit for this use case.
Thanks,
