Does the 908e support mf signalling?

[Anonymous]

ATT is providing an inbound T1 with MF signalling. Does the 908e support MF signalling?

T1 Signalling Flow from ATTL

<--- ANSWER

---> From ATT

<--- From Total Access

  KP = start of pulsing signal = 11 (*)

  ST = end of pulsing signal   = 12 (#)

  NPA NXX-XXXX = Phone number

Thanks in adance

MF signaling is not available on the TA900. The tones used for MF signaling are different from standard DTMF (touchtone).

I haven't used MF signaling since....  Well, look closely at my avatar. 🙂

That's an old-school robbed-bit wink-start T1. If you can get AT&T to change it to DTMF the TA900 will happily support it.

I'm surprised... MF is quite popular in telco signalling on a T1 application.

Getting AT&T to change is difficult and does come with some risk.

Are there any other products that support MF?

I'm not aware of anything similar to the TA900 supporting MF and SIP. Have you considered converting to PRI? Far more widely supported and flexible, includes caller-ID features, near-zero post-dial delay.
