When it rings more then 40 seconds, callers receive :number is not assigned

Hello,

My customer does have the following problem : after it rings more then 40 seconds, callers receive a "number is not assigned" message from the E1 provider.

I have the debug isdn q931 in which we can see that our voice gateway sends an :

Cause i = 0x8081 - Unallocated/unassigned number message.

How can I increase this time to about 2 minutes ?

Many Txs in advance !

Dirk

Re: When it rings more then 40 seconds, callers receive :number

We can change the T310 timer on the gateway by "isdn t310 120000" command and check with "sh isdn timers" command. And note that "120000" value refers in msec, so that this changes to 120 sec.

Please refer the following doc for more info...

Hello, this seems not to be the right timer. Does anyone has got another idea ?
