Hi All,
I'm having a strange issue with my 3CX phone system. I have certain numbers I call (mostly 1-800, 1-877), that are hit or miss when it comes to receiving the DTMF dial tone signals. Sometimes they work and sometimes they don't. I really can't seem to consistently create the problem one way or another. It just either works or it doesn't. There is one number (secondary VOIP provider (1-877) that seems to never accept my DTMF dial tone responses.
Basically its just a big pain because there have been times where I gave up after trying to call 8 times and just used my cell phone instead.
We are using Cisco SPA514G phones mostly. We have a few other models but it happens with them as well. 3CX support asked for Wireshark captures and they said the DTMF signals are being sent from the server. Which by the way is just a Windows 2008 R2 server box with the 3CX software installed on it. Basically acting as our internal PBX system.
Our VOIP provider is Thinktel which is pretty large up in Canada. We do have a Cisco 1811 Router in place. We also have 2 ISP's (ADSL and CABLE), all traffic goes out CABLE except the traffic being generated by the server with 3CX software installed. That goes out the ADSL only.
Any ideas why this may be happening? I can't find any settings in the management side of 3CX. HELP me please!!
Thank you!
