Re: VoIp proposed to replace T1 iSeries uses

Does not belong on PCTECH if you are looking at the iSeries VOIP solution from 
3COM.

Probably belongs on PCTECH. 

Combining your voice and data is fine as long as your provider (or you) 
sets up the router correctly. 

Voice needs a higher priority (QoS = Quality of Service), but can be 
limited from hogging all the bandwidth using Traffic Shaping. Arguably 
if you have this problem, you probably need more bandwidth as nobody 
will want their calls dropped. 

For a SOHO you could look at PBX systems like Asterisk and do it yourself.

Customer had salesperson in today offering to replace all T1s with their 

managed voip system. 

Currently one T1 for phone system, one T1 for data (lan access to web, 
iSeries 

webserver 

and ftp up & down, remote access, etc). Also current T1 provider is our 

managed firewall provider. 

As we go thru this analysis - what should I watch out for? 
When they talked about mixing voice & data, and voice taking priority, I 
get 

nervous. 

Also, this proposal is a "managed" service, from their location. 
And finally, salesperson's claim their internet phones, with no 
configuration, 

can ethernet plug into 

any network in the world and autocfg (cat5 into pc plugs into phone, then 

another cat5 to pc). 

I would think a lot of router setups, home dsl or broadband, or firewalls 

might block this. 

My responsibility is keeping iSeries and all services secure & always 
running.
