What are the pros and cons of connecting a 3COM NBX 100 running ip on the fly with a commercial voip service running SIP?
I'm planning to change my 3COM NBX 100 line connection from voice T1 to one of VOIP service provider. I'm thinking that the proprietary voip protocol of 3com would mix with probably SIP. Has anybody than this before? How's the performance? Is there any late latency issues? Thanks.

this is the main problem and pros of Release 6 with Sip
For the following 5 Â reasons we are interested in the version 6 update
1-camp on
2-whisper page
Not supported in SIP mode
3-Wideband audio is available only for internal and VTL calls on these 3Com devices:
"Â 3102B Business Telephone 3C10402B
"Â 3103 Managers Telephone 3C10403A
Note that SIP trunks do not support wideband audio. Anyway, G.722 is a waste of BW on WAN links.
4-Codec Control will enable us to better handle sound from cairo and alex !!!
The NBX NetSet utility gives you increased control on how you manage the balance between voice quality and data
compression by allowing you to prioritize how a connection chooses one of the various codecs available in the NBX
system. You can prioritize by bandwidth or by voice quality system-wide and for Virtual Tie Line connections, and
you can override the system wide setting for individual devices. Then, when a connection between two endpoints is
being established, the system chooses the level of compression and bandwidth that most closely meets the
capabilities of the devices and the priority you have established. The NBX NetSet screens below show the System
Wide Audio Settings screen and the Custom Settings screen.
We are already using VTL with G.729 and silence suppression. No additional compression can be achieved.
5- NBX pcXset Soft Telephone Client
The optional pcXset Soft Telephone Client, a Windows application, supports enhanced audio compression
- Â Â Â Â Â (G.729A/B) and the user interface has been enhanced.
True. Personally, I've been waiting for this feature for a long time.
What I dont like is the SIP implementation that will cancel many features (but we can install it without SIP)
Please answer my next questions
For SIP operation, the NBX V3000 requires a memory upgrade (650 US$)
1- Â Â Â Â Â We use messaging (how much money the ip messaging)
NBX Messaging is not available on an NBX system running in SIP mode. For messaging features, (voice
mail, auto attendant, Music on Hold, and ACD Delayed Announcements), you must integrate an external
messaging system, such as 3Com IP Messaging 3.0, which is sold separately. The NBX system can
communicate with the 3Com IP Messaging system to automatically create mailboxes. The 3Com IP
Messaging Server can be configured to synchronize periodically with the NBX system.
IP Messaging Bundle (9,000 US$) for NBX includes:
- 12 ports of Voice Mail/Auto Attendant/Delayed Announcements
- Server
- Find me/Follow me and other advanced functionality
2- we use internal paging
Internal paging is not supported. External paging is supported
SIP devices cannot receive internal paging.
3-We would like to have this feature but cannot without sip
A user can login at different phones (Hot Desking), but only one login at a time is allowed. If a user is on a
call, and then that user logs into another phone, the first call will be disconnected. This feature is not available
in an NBX system that is not running SIP mode.
This feature is available only in SIP. A workaround in standard mode would be a hunt group between the phone extension and the pcXset you have on your laptop.
4- this is our connection to cairo
NBX Virtual Tie Lines are not available on an NBX system running in SIP mode. However, you can achieve the
same result, connecting different NBX systems, by configuring each NBX system that is running SIP mode as a
trusted SIP interface. A trusted SIP interface can include SIP proxies, SIP applications, SIP Gateways,
AudioCodes Gateways, and any other 3rd party SIP device, including 3Com VCX IP Telephony systems
Yes, SIP trunks will do the same job of VTL with proper configuration.
5-what are the devices that we have !!! compared to the list below if we decide to implement sip
SIP Mode Supported Devices
3Com telephones that support SIP and RTP (see table), operate the same as they do in a traditional NBX
environment. They support the full range of NBX telephone features except for internal paging and being limited to
three-party conferences when using the NBX conferencing feature. SIP-only telephones (the 3108 Wireless
Telephone and generic SIP telephones) can make and receive calls, use conference, transfer, and hold. Older NBX
devices do not support SIP and RTP and become disabled if they are connected to an NBX system that is running
in SIP mode.
This table shows the 3Com NBX devices that operate with an NBX system in SIP mode:
NBX Device Part Number
2102B/PE Business Phone 3C10226B/PE or 3C10228IRB/PE
1102B/PE Business Phone 3C10281B/PE
2101B/PE Basic Phone 3C10248B/PE
3100 Entry Phone 3C10399A
3101 and 3101SP Basic Phone 3C10401A, 3C10401SPKRA
3102 and 3102B Business Phone 3C10402A, 3C10402B
3103 Managers Phone 3C10403A
3106C and 3107C Cordless Phones 3C3106 &Â 3C3107
3108 Wireless Telephone 3C10408A
pcXset Soft Telephone Client 3C10316 (single license)
3C10154 (site License)
1105 Attendant Console
3105 Attendant Console
3C10123A or 3C10124
3C10405A
(When connected to a supported 3Com telephone)
1-port Analog Terminal Adapter 3C10400
V3000 Analog ports 3C10600A/B
V3000 BRI-ST ports 3C10601A
V3001R System ports 3C10602A
3C10603A
NBX 4-port Analog Terminal Card 3C10117C
NBX Analog Line Card 3C10114C
NBX T1 Digital Line Card 3C10116D
NBX E1 Digital Line Card 3C10165D
NBX Media Driver 3C10319
Polycom IP4000 Speakerphone 2200-06632-001
In short, the devices supporting SIP are:
- Any NBX card that ends in D or higher (e.g. 3C10116D)
- Any 3000 series phone
- Any 2000 series phone which part number ends in B or PE
6-what is the cost of implementing SIP and what including
Licensing on an NBX System in SIP Mode
"Â A 3108 Wireless Telephone uses an NBX Group 1 license and one system device license.
"Â Each generic SIP phone uses one NBX Group 2 license and one system device license.
"Â Each 3Com telephone uses one Group license and one system device license.
"Â A third party voicemail system or the 3Com IP Messaging application requires an NBX third-party messaging
license.
"Â A PSTN gateway requires one system device license per audio path trusted end point. SIP gateways, SIP
proxies, and third-party SIP applications can be trusted devices. At initial configuration, each trusted end point
must assign the maximum number of audio paths that it can have open concurrently. Each audio path, called
a SIP Virtual Trunk, is tracked against the licensed system capacity device limit, up to 1500 devices. For
example, if the trusted end point is configured for 30 audio paths, the 31st request receives a busy tone or is
redirected to another dial plan route if one is configured and available.
"Â Multi-vendor SIP soft-trunks such as Cisco VIC Cards, VCX-to-NBX-to-VCX dial plans, and MCI SIP trunks,
require one system device license per audio path trusted end point.
- The NBX100 will need to be replaced. Two options are available:
- (1,995 US$) V3000 (just like the one you have in Alex now). Bundled with 15 Group 2 licenses. If more than 4 CO ports are needed, will require an external expansion chassis.
- (4,995 US$) V3001R (RAID ready, HDD not included). Has neither built-in licenses nor Analog ports. Will require an external expansion chassis and relevant licenses.
- R6.0 upgrade license for the existing V3000 (1,000 US$)
- Memory upgrade for V3000 systems. (650 US$).
- All non-SIP devices will need to be replaced. We need a complete list.
- All existing licenses will need to be revisited. We need a complete list.
- A DHCP server is required with each NBX.
- WLAN if 3108 will be used.
A very good feature in R6.0 is the new file system, which is more resilient to power failure conditions, protecting the DB from corruption.

as you can read out of this NBX 100 does not support SIP in release 6.0
this was a thorough comparsion of implementing Sip on Two site one with NBX 100 in Cairo Egypt and the Other is NBX 3000 in alexandria Egypt (another City) with a VTL connection 1Mbps between Bothsite for data and Audio

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
