RE: [Asterisk-Users] Asterisk Integration with Lucent Definity g3 si

Title: Message

We have had quite a bit of success with our T100P and TE410P cards interfacing to Nortel Meridian PBXes and also to a Livingston Portmaster 3 using ESF/B8ZS and various combinations of E&M wink and ISDN PRI (usually in 5ESS mode).

 

In the near future, I may also need to interface to a Definity via a T1.  I was planning to use PRI--is that an option for you on your switch?

Subject: [Asterisk-Users] Asterisk Integration with Lucent Definity g3si

Hi everyone,

        We have been working with Asterisk for a while now and would really like to expand its capabilities by fully integrating it with our Definity g3si and are wondering about other peoples experiences with similar setups. Thus far we have only been able to achieve a partial 1 way integration, but ultimately would love to route inbound voip calls to the asterisk out of the lucent. Obviously the tighter the integration we can get the better  we can leverage our existing resources and start migrating aspects of our operations to voip entirely. Comments and suggestions from you definity experts out there are very appreciated.

The setup:

Asterisk 0.7.0 on a vanilla gentoo box with a configured T100P digium card hooked up directly without csu to a TN464 DS1 interface card.

With alot of experimentation it connects (With some timing sync issues) with the following settings on the DS1:
Bit rate: 1.544
line coding: ami-basic
line compensation: 1
framing mode: d4
signalling mode: robbed bit

Interface companding: mulaw
idle code: 11111111
slip detect: n
near-end CSU type: other

We then set up a trunk group, but I believe because of the limitations of the card/setup we can only use group type: co which limits us to outbound on the trunk, or inbound to 1 mapped extension, no DID or more advanced switching. The temporary solution to this has been to use some of the lucents built in vectoring capabilities to send specific extensions to the asterisk. Any recommendations for increasing our integration? Cards/setup etc? Thanks very much. Being able to send voip calls on the asterisk to queues on the Lucent would be fantastic.
