T1 ISDN PRI No Outgoing calls

Hi,

I have configured a Voice T1(ISDN PRI) for the PSTN calls on the Cisco 2851.

I am able to recive the incoming calls but not able to make the the outgoing calls.

Can any one help me in resolving the issue.

Re: T1 ISDN PRI No Outgoing calls

Hi Abhis,

While checking the debug we are getting this error:

*Jan 24 14:54:51.960: ISDN Se0/1/0:23 Q931: RX <- RELEASE_COMP pd = 8 callref = 0x800F

Cause i = 0x83E020 - Mandatory information element missing

Are you using NSF? BTW I also dont see the calling number, although normally is not a mandatory IE for that type of Switch

ISDN Network-Specific Facilities Information Element
