Outgoing call issue 1

[teckgirl]

I have a client where Outgoing calls fail 2-3 times before going through. When ever a number is dialled the first time I get a fast busy, but if you hang up and try again the call goes through.

 

[T1PSTN]

How are your calls exiting the system? Via a gateway? What protocol (MGCP, H.323?) Are they destined to the PSTN? Or another site via WAN?

[T1PSTN]

Okay. at the router:

debug isdn q931
term mon

(cancel with undebug isdn q931)

What do you see during the failed calls versus the successful attempts?


--T1PSTN

 

[jfp23]

Have you checked the call volume are they close to maxing out the 24 lines available on the PRI.

 

[teckgirl]

Almost 90% of the calls fail, so the error is the same most of th time?

Here is a local call going to another location on the same CCM Server. Of course this call connects just fine.

You may need to do a shut/no shut on that serial interface. Seems like your DSPs and B-channels may not be lining up. I've seen similar things before, and resetting the controller or interface seemed to clear them.


--T1PSTN

 

[T1PSTN]

Also, you can try this...

conf t
voice-port 0/0/0:23
bearer-cap speech
end


--T1PSTN

 

[teckgirl]

Thanks I'll try both tonight when the client is closed.

 

[teckgirl]

Thanks I think it worked!

 

[frankbil]

One other item to note. 12.4 has a bug noted on Cisco's site which relates to outbound PRI calls. We had a similar issue. We ended up moving to IOS 12.3T.
