License Help - For OmniPCX Enterprise R9.1

[Hars1959]

Hi guys,

First of all, thanks for the help. Here is my case:

I had made an integration of an OmniPCX Enterprise R9.1 with a Third-Party PBX trough a SIP TRUNK. Everything it's working like a charm (Transfer calls, conference, hold on calls, call backs, etc etc). Now, I need to be sure of the licenses i need for the OmniPCX in order to assure that at least 700 users can talk trough that trunk Link.

The license for SIP Trunk on my OmniPCX are:

185 SIP Gateway = 1
188 SIP network links = 4

I used only this two lines to made the interconnection and test the scenario.

And my questions are:

1- I understand that the "SIP network links" tells me the max. number of concurrent calls. So i supposed that i need at least 350 channels aprox (acording to earlang law). Is that true?

2- I am not sure what SIP Gateway license is for. Can someone explain it a little more clear to me?

3- Apart from "SIP Gateway" and "SIP network links" Licenses, do i need any other license? maybe for codecs or any other?

4- The most important question. Can i still buying licenses for this Release? (R9.1) or do i have to make an upgrade first?

Thanks to all!!

1. Yes
2. Number of SIP trunks
3. No. HW for compressors only.
4. Will depend on your BP. I think yes. But without support I doubt it. To sell something new to an expired user will ask for support contract probably. No sense to sell something without support.

really sure with point 3? i think he'll need g723 and g729 server licenses for activating the compressor hardware.?.
another pro to point 4is that alcatel-lucent has implemented more features in sip in a newer release.

Ohh well, I assume he already has tested on desired codec and only wish to increment his base. Same for new features, as he says all works fine I see no benefit on selling advanced features on simple implementation.

yes, i can agree with you cav. so it just depends on his future plans with the oxe.
Now it's your turn Hars1959.

i agree for codecs , especial if you have hybrid pabxs :lot of kind of users analog , tdm needs compressor , if full ip& sip direct rtp should help
@cav are sure for point 2 i had sofware lock 185 =1 (sip gateway) and as per system doc this lock can have the value 0 or 1, but i can creat 3 external sip gateways with no panic flag ; i think 185 is only to active the internal sip of oxe ;
for hars 1959 you should control 188 swlock and related compression sofwarelock g723,g729 serv and client may be you need also to add some hw

According to docs is for SIP Trunks, not for SIP External Gateways.
Usually I receive licenses with bigger numbers so never had the scenario where I could overpass the lock number...so no real experience there just theory
