cme h323 transfer to voice mail

whanson · ‎03-31-2008

Have CME system. Internally works fine transferring to voice mail on busy or noan. PSTN calls to system, likewise no problem. Have a pbx connected via t1 at another site using voip to get calls to cme. Calls work find however on busy or noan disconnect rather than transfer to voice mail. I have allow connections coded for h323 to sip and sip to h323 but it doesn't appear to work. Thoughts thks.

sorry, got a hint from another forum. Issue is 711 to 729 transcoding

What did you need to do to resolve the issue? I have the same situation and I've been hitting my head silly trying to figure it out.

Thanks,

Roger

Well, I can't comment on his problem specifically, but most of the time, you need to assure that the dial-peer going to your CME specifies the codec g711ulaw and that your session protocol on the dial peer is sipv2. So you'd have something like the following:

dial-peer voice 2000 voip

destination-pattern 5000

b2bua

session protocol sipv2

session target ipv4:x.x.x.x

dtmf-relay sip-notify

codec g711ulaw

no vad

If you're after something additional in regards to the transcoding let me know, but I think this should point you in the basic direction to start with.

HTH,
