Need a little help trying to figure out why I can't enable a GATM4 in a BCM 450.

Situation is this;
I had to renumber the working GATM4 line numbers to make room for more VOIP line numbers.

The VOIP line numbers currently show as 1-4, (I want the VOIP lines to expand to be 1- 48) the GATM4 was using lines 5-8 (which is why I think, is the reason I cannot renumber the VOIP lines currently) and the DTM/PRI is using 121 - 143

In order to make room for the VOIP trunks, I Deconfigured the GATM4 which, by the way resides in location Main MBM 3, bus 30.1 with all dip switches set to on.

I then renumbered the GATM4 line numbers to start at 049-052, which it allowed me to do, I then tried, several times to enable the GATM4 unit, but it will not completely enable, it alwyas shows as "enabling" but never goes the an enabled state.

Any thoughts or suggestions would be helpful.

Thanks in advance

Do you have the actual telco lines jumpered out to the card? I think the card needs to see the actual 48 volts of the analog line in order to enable.
 
Problem 1 of 2 resolved.

The card now shows enabled after letting it run for the better part of an hour. Not sure why, but all is good with this part.

The second part as to why I started this change in the first place was to make room for added SIP trunk channels (16)

After renumber the VOIP trunks from 1-4 to 1-48,

I see that the renumber has taken place,Now 1-48 VOIP trunks, the problem is that I can not seem separate the trunk groups. I.E Sip, vers H323. I currently have 4 H323 trunks that use BlocC and want to add SIP trunking to BlocD, however any changes for one line number changes the entire group. How does one differentiate H323 trunks from SIP trunks? I.E I what H323 to go out BlocC and SIP to go out BlocD

This is my first SIP turn-up, so please forgive me if this seems simple to do.

Thanks for your reply's

Just like PRI. You can't separate them into different groups. They don't call them "Bloc" for nothing. If you change one channel, they will all change, as you have seen.
 
Ok,

So how does one route to separate trunk groups? I.e Sip Vers H323?
If I have keycodes to 4, H323 trunks and 16, SIP trunks, how can I make sure I have access to all these trunks and routes accordingly?

Can I make 2 separate VOIP trunk groups, 1 for H323 and 1 for SIP?

Please elaborate on how this is accomplished. Thanks for your time and input.
 
IP trunks are not like analog or other digital trunks. You have one IP connection to the BCM so all IP traffic is sent out on that connection. That's why all your IP trunks are set up as one entity.

You can have a mix of SIP and H.323 but the routing to use them is done under the IP routing table under Resources>IP Trunks. In there you create routes and within them, you set destination IP addresses and protocols to use etc. You also have to use the regular routing tables to sent your destination codes to the right trunk pools too.

If you've never done this before. I strongly suggest you call in a vendor with the proper expertise. If you are a vendor, ask one of your co-workers who has because it can get a bit frustrating.
