Problems with DTMF tones

<< < (4/9) > >>

Kaizer:
i have obi with gv as sp1. i'm experiencing the same issue with using a calling card for international calls. obi via gv connects to the local call center. the other end has a hard time validating the pin that i must enter. a certain pause between each digit is required but i've only had 1 successful try.

RonR:
Kaizer,

It's been suggested that enabling the following setting may help:

Service Providers -> ITSP Profile x -> General -> X_UseFixedDurationRFC2833DTMF : (checked)

ChrisThompson:
That setting is enabled on both my SIP accounts.

RonR:
The suggestion was originally made in the context of Google Voice DTMF problems, but I suspect it can't hurt to have it enabled in any case.

I haven't experienced any DTMF problems with either Google Voice or SIP providers and haven't found this setting to make a difference either way, but let's hope it helps Kaiser.

earthtoobi:
i used to have similar issues in the past especially when entering conference PIN number.
Making it to in-band DTMF solved my problems.

(Even after the above setting i have issues once in a  while when i type in PIN numbers real fast,but i don't consider it a problem.)
