INAP configuration with Digium TE420 card on Asterisk

Asterisk Asterisk Support
1

I am currently working on Missed Call project in India. I have setup the whole project on Asterisk (using CentOS 6.6 as a base OS).We have deployed this project with different telecom provider on SIP, SS7 etc.

One of the telecom provider is providing us the connectivity on SS7-TDM using INAP protocol.They have provided us the GT and SPC . Now the challenge is we don’t have any library which supports INAP. I have a few doubts which is listed below:

  1. Does Digium card(TE420) supports INAP
  2. Do We have to purchase some other hardware device to handle this INAP protocol.

Currently, we are getting following logs for the same configuration :

I hope, I have described you in details

I suspect you have to purchase software that supports it.

For the hardware question, you should ask Digium the company, not the Asterisk opens source community.

However, if it is built on SS7, I imagine that it will differ at a level where the hardware is not involved.

Thanks for your reply !
Could you please tell me that whether there is any library of SS7 which supports INAP protocol.

That sounds more like a developer question.

Hi David,

Please suggest me the solution regarding this.See, I have actually two doubts:

  1. Does Digium PRI card (TE4200) supports INAP
  2. If yes, Where do I find the suitable library.

If this is not the right place to ask this question then where should I post this doubt :cry: . Please answer accordingly.

For (1) ask Digium commercial support, although no may mean that it is not appropriate to implement it in the card firmware.

For (2), try the developer mailing list or IRC channel, although I think you may end up having to use Google.
