SIP and DTMF tones

[HUGWideBoy]

Site A is a 1000e rel 5 with Callpilot 5

Site B is a 1000e rel 5 connected to site A by a traditional ISDN30

Connected to Site B is a "find me anywhere" system, which uses SIP trunks to connect to Site B.

Voicemail works fine between site A & B.

If the "find me anywhere" system trys to send a call to voicemail, any duplicated digits get drops.

ie extn 12345 works fine, but if if it was trying to send a call to mailbox 112233, then callpilot says "there is no mailbox 123"

If I run a trace on the D channel between site A & B I see all the digits in the trace.

talking to the support company for the "find me anywhere" system, they say that there system uses RFC2833 to send the DTMF tones. My understanding is that a 1000e rel 5 also supports this standard.

Any ideas of what the problem could be ?

i face this problem, nortel with cisco the integration with SIP there is no DTMF detection between two sites

Forget the DTMF, it is not used. Everything is done through the DCH, if you say you saw the correct digits in the messaging then it's time to look elsewhere

I'll log this one with BT then, as I definatly see all digits on the D channel.
