SIP Trunks

[andy4uk]

Hi Guys,

Just a stab in the dark, something i have not really looked into yet - I have a customer who want to purchase a Mitel solution and they currently have 2 Nortel system which are SIP trunk enabled, he has asked if we can use the SIP trunking to link his Mitel system to the Nortel system???

I have configured SIP Trunks to providers and other SIP type servers and have not had any issues.

The question is.... has anyone implemented SIP trunks to work between different type Voip systems and have they hjad any problems..!!

Cheers

Andy

It will NOT work. Not because Mitel won't support it, but because Nortel will not support it. Nortel is very behind with Generic SIP.

Hi TheMitelGuy,

I was speaking with engineers yesterday that support a customer Nortel system and they said that the Nortel supports SIP Trunking..!!

I might need to do some further investigating.

Yes, Nortel has SIP trunking (even the BCM has SIP trunking), but it is between Nortel switches only at this time. That is, unless it has changed in the last few months....

Hi TheMitelGuy,

Thanks very much for this info, these guys made the Nortel out yesterday to be the system that could do everything.

Nice that I'll be able to prove them wrong...!!

Do you know of any documentation that can advise what the Nortel is cabable of?

I will get you something later on today.

Nortel is very easy to disposition when it comes to Mitel. I always say "Nortel's options are on or off, Mitel's are on/off, with timers, switches and options" (we can be more flexible then just on/off).

While there are internationally recognized "Standards" it seems that within each so-called standard there are a number of optional components. In order to be fully inter-manufacturer compliant both systems must support either a complete subset or at least an identical subset of the standard. This is exactly what we ran into several years ago in a futile attempt to join a Nortel 81C with a Mitel SX2K over QSIG. At the time we already had the Mitel working successfully with two other competitors so when it did not work with Nortel it was pretty easy to figure out who was "compliant" and who wasn't. I do not know if that's ever changed. Our solution was to do a forklift replacement of the 81C with a 2K.
