Fast busy on H323 trunks on inbound calls

[atascoman]

I have a BCM200 connected via H323 trunks over and NRS to a group of CS1000 systems. I can call the CS1000 sites using the H323 trunks, but when they attempt a call to the BCM they get a fast busy. I have the BCM in the NRS and it is registered. I setup my target line as public and entered the 4 digit extension/DN value in the recieved number field. I also assigned the target line to the set and made it ring only. ANything I am missing?

on the CS1000's do you have CDP entries for the BCM?

 

[atascoman]

yep

If you have MCDN, I believe the target lines should be private.

 

[norstarboy125]

you said that you set up the public target lns. make sure that you do the private revd digits also...has this worked before.

Is your CDP entry sending to RLI that is associated with H323 route?

 

[atascoman]

This is a new install. The RLI is setup to route to the IP trunks off the CS1000 which then goes into the NRS. My call routing from CS1000 to CS1000 works fine, I have verified that my entries for the BCM are in the NRS.

The only caveat so to speak is that the CS1000 is on SIP trunks and the BCMs are on H323. This is also the scenario when calling the other CS1000s as they are on H323 as well. I have them setup as tandem sites with the central locaton where the NRS is located as the tandem endpoint.

You will need at least 1 CS1000 site with H323 & SIP trunks to use the tandem call feature available in NRS.

 

[atascoman]

Right we have that. Does the CS1000 that is the tandem site need to have the CDP entries to match the system where the call originated since it has to send the call back out the H323 side or does the NRS take care of this part?

 

[pronei]

The Tandem host PBX will need CDP entries to connect both external sites.

 

[atascoman]

Thanks, that did the trick. Guess I should have paid attention to your earlier post a little more, I just had the one CS1000 on the brain not the tandem site.

I ran into another problem on this. None of the BCM's could call the site where the NRS was located but could call other sites. Turned out to be that the CODEC settings were mismtached. The payload was set to 30 on the BCMs and 20 at the NRS site. Seems to have fixed that issue.
