no dtmf tones when calling out

[webguyz]

Have the Skype Gateway working well, but when using it I can not generate touch tones when going to a site like an online pharmacy. Have the latest version of 3CX and Skype Gateway.

Anyone else having this problem?

Thanks!

What device, ATA/VoIP phone are you generating the tones with? Sometimes changing the way the device sends DTMF information , in-band, or as SIP messages, can make a difference. Someone found that certain analogue phones, when using an ATA, generate such a short burst that it doesn't get through. This was via a Gateway to the PSTN, but the principle may be the same.

Using an ATA (PAP2). This same phone works fine when I access my other outbound Gateway, a SPA3102 connected to an Ooma Telo, and it generates touchtones without a problem leading me to believe its a Skype problem. Will take another look at the 3CX settings. If other people are getting touchtones using Skype gateway then it must be an issue on my side. Just wanted to make sure it wasn't a known issue.

Thanks!

I've personally have issues with DTMF not getting though an SPA3000 (or 3102) going to a Magicjack. The tones are there, but are too short a duration for the MJ to detect.

Hi

As far as I can remember, Skype client cannot send DTMF (properly) to (some) PSTN numbers, at least in some older versions. To verify this, please do the following test:
- stop the gateway and from its console, for the corresponding channel, click the Skype button to open its corresponding Skype client.
- from this skype client, try to call the online pharmacy number and see if DTMF tones works ok - if not, there is the Skype problem, not involving the gateway.

I was able to get this to work with my Cisco SPA525G phone by changing the DTMF method to "Inband".
