SIP DN "call forward all" supplementary-service


we try to setup a sip account with cucme 8.0.

it seems to work good but supplementary-service is not working and codec is a problem.

we cannot set call-forward all with sip.

we use g711 alaw codec for sip and with this codec it is not possible to access the voicebox.

since sip is using alaw and dial-peer to unity uses ulaw.

we use voice-class codec with sip but if alaw is used access to voicebox is not possible.

Here is the configuration:

voice call send-alert
voice rtp send-recv
voice service voip
allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip
supplementary-service h450.12

Please help me with that

Re: SIP DN "call forward all" supplementary-service

Well codec is not a problem anymore? - i have no idea why - it is working.

What cannot be done is this "call forward all to voicemail".

if i use supplementary service from Sip Phone to do a call forward to 99 ( voicebox unity ) it is redirecting to unity.

The unity then takes the call but it goes to the voice menue instead of voicebox.

so you cant leave a message - callers will hear " please enter your pin ".

The other thing is, that the call is redirected, but it will not show in config of cucme.

This: call-forward b2bua all 99 is never set - but it is redirecting????

What is this all about?

And PLZ can someone move this post to ip telephony - Video is the wrong section.
