T46G and PBX Feature Codes

[tonycolorado]

I am having an issue with not being able to use certain PBX Hosted in-call feature codes through my Yealink T46G. Hoping that someone can point me in the right direction.

I use IncrediblePBX and it features several in-call feature codes - For example

• *1 Records
• *2 Initiates an Asterisk assisted transfer
• ## Initiates a blind transfer
  

When I enter these codes on a softphone or my GrandStream SIP DECT Phone the proper behavior is triggered (The PBX hears the tones and does what its supposed to do) however when I enter the codes on my Yealink nothing happens EXCEPT when I do *1 to start a recording - that one command works.

To Illustrate, here is what I can do on my Softphone
1) Initiate a call
2) While talking to someone, press ##105 to transfer them to extension 105
3) The caller is transferred
4) Or, while talking to someone I can press *2 to hear a prompt asking me what extension to transfer the caller to. I enter the extension and the caller is transferred

Here is what happens when I try the same thing on my Yealink T46G
1) Initiate a call
2) While talking to someone, press ##105 to transfer them to extension 105
3) The caller is NOT transferred (nothing happens)
4) Or, while talking to someone I can press *2 . Unlike with the Grandstream, I hear no prompt.


It seems that my Yealink is somehow not sending or otherwise intercepting my * and # Keys (except For *1 to initiate a recording - thats the only one that appears to work) - I have validated that both my PBX, PBX Extension Settings for this Phone and YeaLink Config panel are all set to rfc2833

I do realize that my T46G has a built in Call Transfer feature, however I would prefer to use the PBX assited version of this because it enables me to disable the ring tone that transferred callers hear.

Any tips?
