UCCX 5.0 SP2 Not accepting PSTN Calls from MGC Gateway

dheavey30 · ‎03-19-2009

Hi, I have a strange problem whereby if I dial my scripts internally they all work fine but coming in from the PSTN the caller just hears a fast busy tone. This is a new installation so has never worked. I can dial the IP phones OK from PSTN. Triggers are in the same partition as the IP phones. Codec is G711 all over as its a single site. No location bandwidth restrictions etc. Should be straight forward. UCCX version 5.0SP2, CCM 6.1.3

The gateway is MGCP with E1 PRI (30channels)set to primary net5.

I have 300 CTI ports all in the same partition as the phones as well.

Any ideas??

Hi

Most likely it's a routing, partition/CSS or codec mismatch; however it sounds like you have checked these.

Post detailed CCM (from your call processing CCMs) and MIVR logs (from UCCX) from the time of the test.

Thanks

Hi, i had this problem and it was a codec issue .. try to put the codec inside the voip dial peer .. for me it worked fine after adding codec g711.

Hope it helps

Hi,

I have all my regions/locations setup to use G711, incoming calls to IP handsets are also coming is g711.

If MGCP does not have a dial-peer is there any other way? I would be interested in what you did to resolve this..
