Dear All,
it seems I have some setup problems with my Asterisk PBX.
I can not tramsmit any DTMF tones to the remote called PBX!
This is my setup:
I have a Polycom SIP phone registered with my local Asterisk PBX.
My Asterisk PBX uses a SIP provider to dial other phone numbers.
If I call somebody that has a PBX that requires me to press some keys to be transfered,
then this does not work because the DTMF keys that I press on my Polycome phone get
not transmitted.
Instead I see this message on the Asterisk console:
– Attempting native bridge of SIP/12-c4bf and SIP/gateway4-a40c
– Attempting native bridge of SIP/12-c4bf and SIP/gateway4-a40c
– Attempting native bridge of SIP/12-c4bf and SIP/gateway4-a40c
SIP/12 is my Polycom phone
SIP/gateway4 is the SIP provider
I suspect that my error is probably stupid,
but I need somebody to point it out to me.
Looking very much forward to receive some suggestions.
Best regards
Georg P. Israel
