Connect Freepbx to Avaya CM using PRI

Hi Team,
I’m trying to connect freepbx to Avaya but I don’t have any sip trunk on Avaya only what I have is PRI and I got a PRI on my freepbx I need help on this setup thank you.

You might have H.323 trunks on your Avaya CM.
Check if you have licenses:
Display system-parameters customer-options

This way you could go direct IP.

I do have H.323 trunks but I don’t have any Clan cards open

They are really cheap if you want to buy one.

Thanks Avayax I did check them yes they are cheap but I don’t have any room on G650 to install them is there any other way to do this thanks

thank you dicko I will check this thanks again

Hi:
My customer uses Sangoma A101E connecting with G650, it works.

H.323 is certainly viable, but there will be lots of pain compiling / provisioning it and arranging for BLF and voicemail lights to work bilaterally, whether you choose Asterisk or Avaya to handle those needs

Thanks James i have the pri for both side i just what help with configuration thankg you again

So you recommend to go with PRI right thank you for help

I would go with robbed bit signalling (e&m wink would be ideal) on a T1 or E1 for better dtmf integration between systems and the ability to flash the channels. (Channel Associated Signalling)

Thank you dicko i will try to config pri for both side i will let you know if i need help

I specifically did NOT suggest you use PRI signalling on that span, please read, learn and comprehend why not.

Hi Team,
So I did the connection from avaya to Trixbox h323 trunk then i have a sip trunk from trixbox to Vocera server which has to extension 88XX setup my avaya extension are 4xxx i need to create inbound route so the calls from Avaya they go to Vocera sip trunk then i need help with calls from vocera sip trunk to go the h323 trunk thank you team on advance

Can you elaborate why you think e&m wink is preferable to PRI signalling, in particular regarding dtmf integration?
Is there a downside to using e&m?

It depends on your tie-line, if it can do ISDN then let the B-channel rule, if it can’t then use basic T1 RBS Signalling, it is how TDM spans are configured, it is then a choice as to what your other hardware can negociate, Downside to using RBS is that all channels are 56kbs, there is no co-origination as to what channel is being used ( see “glare”) and disconnects might give you problems, Upside for isdn is Faxes will work better and calls will be shorter on hangup.

I am using Digium G200 PRI gateways to connect to legacy PBX, which send calls to the PSTN.
Sometimes people complain about DTMF digits not being accepted on the far end. They press, but nothing happens, or sometimes only if they do it very slowly.

Don’t have the problem when using h.323 trunks to connect FPBX to legacy PBX instead of PRI.
So the PRI gateways are the culprit.
I might give e&m a try.
