TDE600 to TDE600 to SIP Trunk - no DTMF

TDE600 to TDE600 to SIP Trunk - no DTMF

TDE600 to TDE600 to SIP Trunk - no DTMF


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?

Can you dtmf from local system?

RE: TDE600 to TDE600 to SIP Trunk - no DTMF

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.
