ShoreTel 12 to CS1000 Rel. 7.5 via direct SIP trunks

[TudorNegru]

Hi there,

Well I'm fairly new to this whole SIP thing. I have a CS1000 in my lab that's SIP enabled and a freshly installed ShoreTel system which i managed to get talking via QSIG (yehha ) and am thinking/trying to get them talking via SIP now directly without any intermediate device other than a router (would this be possible??) to bind the TLAN Node to the SIP Proxy on the ShoreTel side.

I've seen a lot of threads on integrating the CS1000 to Cisco CUCM but no "recipe" for SIP-ing to a ShoreTel directly.

Now since i have H.323 ports on the Nortel/Avaya, I'm using UCM. My dialing plan on the Nortel is 40xx 41xx and on the ShoreTel it's the 17xx range.

I've tried using some settings from a 7.0 to CUCM integration document but nothing seems to work so I'm back at square one.

Any tips, cheat-sheets or advice would be very much appreciated.

Many thanks.

Did you ever get this working? If not, what exact issue did you have.

Hi,

I got this working but only like about 50 %.. i was able to make calls from the ShoreTel to the Nortel, calls would ring, voice was fine (no one-way speech, users could hear each-other perfectly) but when placing calls from the Nortel to the ShoreTel, nothing would happen.. I think this might be something to do with the SIP Invite message the Nortel is sending out to the ShoreTel but this is simply way over my head to fix.

I know that in the ShoreTel there's an option to create custom SIP Profiles but i haven't the slightest idea where to start from.

How did you get along?
