DCH MSGI "PROTOCOL ERR UNSPEC"

[rumelihavasi]

Hi Everybody,

I have a system that was working fine.
However provider changed the Backbone switch and we dont know what kind of carrier system they brought.

My system whoever calls from specific country incoming calls rejected and DCH gives Protocol error unspec message.

Can anyone help me what could be the problem.

Best Regards

It sounds as if the customer hasn't got any idea what they have just done. The new carrier should have provided a Protocol based on the current existing PRI settings as there are many different ones available and also some ISDN circuits need different PRI cards.

I don't think that many of us are going to be able to help you.

Hi,

thanks for your reply. I will talked to the Service provider and update here if there is a change.

So does the call process or not? If it does turn off messaging and move on. If it doesn't process then there is obviously a mismatch in protocols. In the US most use NI2

Calla sometimes connects sometimes not. system in Kazakhstan. Within the Kazakhstan all incoming calls are OK without any problem. However any calls from outside of the country gets an errors. 1 of 3 calls are success.

only chance for you is to print the DCH, route,member config & also include capture the DCH messaging for working & failed calls here.

Good luck
