[asterisk-users] DTMF problem

[Zeeshan A Zakaria]

This DTMF problem has always been there and there is no real solution for it, other than using those expensive PBX systems like that from Avaya, Cisco, etc. This problem happens when you are sending inband DTMF tones. Via softphone you are sending out-of-band DTMF which is basically SIP messages.
