TDE600 to TDE600 to SIP Trunk - no DTMF

TDE600 to TDE600 to SIP Trunk - no DTMF

TDE600 to TDE600 to SIP Trunk - no DTMF

(OP)
Hi,

I have two TDE600 that are connected to each other via private trunk with a virtual IP Gateway. I allowed that phones on System A can access the SIP Trunks from System B. However, once a phone on system A has dialed his destination number system A can't send further DTMF tones to the destination on the SIP trunk on system B. Does anyone know if there is chance to fix this?

Thanks

Norbert

Yes, I DTMF is working on the local phone system and also when I ended up in the mailbox of a user of system b. It also works when a caller from system A access the PRI trunk off system b. But it doesnn't work when the caller from system A access the SIP trunk on system b. if a caller on system b access the sip trunk DTMF works.

Thanks

Norbert
