Transfer problems

I have 1 Snom 360 and 6 Snom M3 phones.

When i want to transfer a call between the extentions, i press ##EXTENTION

Example: ##201 - Normally it dials the extention, and i can hangup.

This used to work from every phone. Now it's only working on the Snom 360 phone.

If i press ##EXTENTION on the M3 phones during a call, nothing happens.

I have searched the forums - found a thread suggesting that i restarted my PBX. I have done that, without any results.

Any suggestions? Could it be the phones?

Thanks.

RE: Transfer problems

Without having looked in the configurations of your phones and account, I believe this is related to DTMF transmission and detection.

How is the DTMF set in your extensions and IP phones? Have you recently updated the firmware on the M3 phones?

RE: Transfer problems

The first thing i did with the phones, was to update the firmware to the latest.

It worked with the latest firmware, but then it suddently stopped. On all 6 m3 phones.

They are connected to 2 base stations, which i allso firmware updated.

How can i check the DTMF settings? Is it country specific?

RE: Transfer problems

Well, it seems that in the M3 phone's OS the DTMF setting supports all 3 available options: In-Band, SIP Info and RFC2833.

The above info can be found under the SIP section of the Snom m3/Online Manual. So in your case, try to set the RFC2833 option, both on the M3 phones' web interface, as well as at the "dtmfmode" in their associated extensions.

If you can't find the appropriate setting, on the M3 web interface, let me know and we will try to help you.
