[Asterisk-Users] problem detecting answer on pri card

[Alex Vishnev]

I have seen that before when you mismatch the type of pri flavor. For
example, if you carrier gives you 4ess and you put 5ess in your config.
There are subtle differences in packets. I would check the configuration on
your carrier side and * side.

Subject: [Asterisk-Users] problem detecting answer on pri card

Hi,

I have a digium PRI T1 card connecting to my carrier. However it has
problems to detect the answer signal on some numbers. For example,
1-800-225-2525 is KLM airline's reservation line. It should answer right
away. But * can't detect it is answered and keeps ringing the ip phone. I
put a monitor on the channel, and get the answer messages in the channels.
So somehow the line is answered but * doesn't know. I don't have a problem
to most numbers. The problem only got my attention after one customer
reported it.

A debug on the pri shows,
Ext: 1  Progress Description: Call is not end-to-end ISDN; further call
progress information may be available inband. (1) ]

So maybe the inband information is not detected by *?

Anyone has the same setup, i.e. PRI to your carrier? Can you please dial the
number 1-800-225-2525 and have 'pri debug'? I'd like to compare the results.
I am not sure if it is * or just my * configuration.

Your help is highly appreciated. I am really stuck here.

Thanks,
Richard
