Hi there, what phones are available that have two ethernet ports? I want to do some cabling at a new installation and i heard there are such phones (SIP i guess) out there. That way i dont have to run two cat5 to the user desktop. I think 3COM had one but can't find the web site reference for the two port phone thanks, erick
Update: found the 3Com? 3101 Basic Speaker Phone Provides dual port 10/100 switched Ethernet for one-wire connectivity between the phone and a PC any others not so expensive? does these 3com sip phones work with * ?

Some of the Cisco phones do (7940,7960 etc, also the 7910+SW but this is skinny only).

Personally I would run the two Cat5 runs. I am in a situation where we "only" have two cat 5 cables into each office. Once (if) we start our VOIP deployment we will be using Zultys 4x4 phones with 3 10/100 ports (802.1q capable switch built in) on one office port, and the other will be for the researcher's "main" desktop on our gigabit switches. I would love to be able to connect more systems at Gig, but putting a small gig switch in each office is cost prohibitive, and a management nightmare. Try finding a VOIP Phone that does gigabit... Won't happen for a while. Cable is cheap when you look at the cost of running the cable. If you use two boxes, it will take virtually the same amount of time to run two as it does to run one.

I think the phones from http://ipphone.eezeephone.com would work for that. They are not a very heavy duty phone but the one we have works fine.

Even worse, some two port 10/100 phones re-negotiate link speed on both ports at the same time, dropping CALLS when you restart you PC! There are some splitters you can use at both ends of the cat 5 cable (if you do not use POE, as stated before). DAD1518 on google will lead you to them, about $10 each ($20 per split cable). This allows the use of dedicated ports on your switch. A good strategy on a managed switch is to put your IP phones on a dedicated VLAN with * to avoid some issues caused by high traffic loads on the PC ports. This will prevent PCs (and viruses on them) from impacting voice quality. This also requires considering the placement and appropriateness of DHCP servers for VoIP phones. This strategy is not possible when trying to use the integrated hubs on the phones.> -----Original Message----- > From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users- > bounces@lists.digium.com] On Behalf Of Mitchel Constantin > Sent: Monday, January 03, 2005 9:44 PM > To: Asterisk Users Mailing List - Non-Commercial Discussion > Subject: Re: [Asterisk-Users] phones with two ethernet ports > > I just wanted to point out something cool about the hub in the Cisco > 7940 and 7960 (maybe others too).

I believe your last comment is incorrect. Some phones support vlan tagging, which means you can connect two (or more) network interfaces to the same switch port and have each of them talk on a different vlan.> -----Original Message----- > From: Damon Estep [mailto:damon@suburbanbroadband.net] > Sent: Tuesday, January 04, 2005 7:14 AM > To: mitchel@titaniumsoft.net; Asterisk Users Mailing List -Non-Commercial> Discussion > Subject: RE: [Asterisk-Users] phones with two ethernet ports > > Even worse, some two port 10/100 phones re-negotiate link speed onboth> ports at the same time, dropping CALLS when you restart you PC! > > There are some splitters you can use at both ends of the cat 5 cable(if> you do not use POE, as stated before).
