Hello all,
As mentioned above i have a requirement to connect our current OCS infrastructure to our local PBX (Nortel BCM50).
Now the BCM50 doesn't have v3 of the firmware which would allow it to establish a direct sip trunk to the OCS server and it only has H.323 capabilities (and i believe they are restricted).
At the moment im only trying to establish the h.323 part with the BCM50 which is having a few problems ...
I have a dialplan in the BCM50 and my phone extension is 251 ... so when i try to start a connection to my extension from the router i get the following disconnect ...
csim start 251
csim: called number = 251, loop count = 1 ping count = 0

Now the h.323 setup should be really straight forward as there is no catch (all numbers to the voip dialpeer ...)
Can you give some help please ? Or point me to documents which will allow me to configure the things properly (i think the PBX may have some configuration missing)
Thanks in advance ...

Please don't use csim start for voip calls. This is a legacy command intended for pots interfaces.

Can you expand on this warning? Are you aware of bad things that can happen using csim for a voip call test?

I have a lot of experience with BCM50 and Nortel (at least on this product) really doesn't do H323 or SIP like anyone else. They don't follow standards or allow much configuration. As you mentioned though, your best chance would be with the latest software R3 and latest patches and you should be able to get SIP to work.

Well thats good because I dont really know much about the PBX.
I did see the logs on the PBX and saw that it was receiving the H.323 call and blocking it ... the message was something like:
call blocked: maximum number of calls
But all the H.323 setup was received and processed perfectly.
I do believe that warning may be due to lack of licensing for VoIP trunks (meaning that i may need to put some keys or whatever they call it in Nortel - as when i go to the keycodes i can see the VoIP Trunks with a 0)
I would love to be able to upgrade it to R3 as i know it supports direct SIP trunks but the problem is that i think the pbx here is version 1 which means that the hardware itself is different from version 2 and 3 ... which again means that the upgrade is not as easy as that.
My cisco router also has a E1 card and my idea was to use it as a SIP gateway (from the OCS side) and then use Q.931 to the Nortel side but i don't have PRI ports available on the PBX so i have to go for the IP 2 IP gateway.
I dont have access to the Nortel site to download upgrades or keycodes ....
Anyway this is a cisco forum and i understand that is not the exact place to discuss Nortel issues and i do know now that the problem lies within the Nortel PBX
Cheers

Hi Nuno,
The csim start command predates IPIPGW and a good portion of voip calls. It wasn't originally designed to originate a voip call, and I haven't had much success with it. From my testing, it doesn't look like it will accurately originate a voip call. You can get it to do pots calls with a higher success rate, however.
It's not worth looking at debugs of a call originated from csim start. Too many other things could be going on.

I can try to get you a "try before you buy" 60 day keycode for h323 trunks, I'll need the system ID of your BCM50 and your email address. bsvec@teamonesolutions.com

brandonsvec,
Thanks for that. We are currently trying to make the seller upgrade the PBX or give us proper keykodes.
Though i will send you an email today for those keycodes as even if the seller decides to upgrade ... i can still go on and try it today :)
Thanks again
