Asterisk detecting GSM DTMF but not PSTN over the same lines

Hi All,
I’ve just delved into the world of asterisk and I’m having a few dtmf issues.
Internally, amongst sip phones, dtmf is fine.

Externally, if you ring from a GSM mobile, DTMF is fine, however if you ring from a standard phone, DTMF fails to register.

I am attempting to use a quad port HFC-4S Beronet Card. I’ve been searching the web most of the last week and haven’t found anything that actually helps (although there seem to be a few people with DTMF boggles)

Is there anything special we need to do for these cards to detect telecom dtmf tones?

I find it a little confusing that incoming GSM, which rings in via the same lines works, and telecoms phones don’t. I thought it would be the other way around if anything.

Any help would be fantastic!

I have attached logs of an incoming call via telecom, and an incoming call via vodafone. The only difference I can see is the codec (I think) type.

Telecom seems to send the cal through as “Audio 3.1K” while vodafone uses “Speech”. Would this difference do anything?

my mISDN config is also below should that be of any help.

Telecom: (No DTMF)

Configuration file for your misdn hardware

Usage: /usr/sbin/misdn-init start|stop|restart|config|scan|help

Card Settings

Syntax: card=,[,…]

count your cards beginning with 1

either 0x1,0x4 or 0x8 for your hfcmulti hardware,

or the name of your card driver module.

ulaw - uLaw (instead of aLaw)

dtmf - enable DTMF detection on all B-channels

pcm_slave - set PCM bus into slave mode

ignore_pcm_frameclock - this E1 is NT without PCM frame

clock

rxclock - use clocking for pcm from ST Port

crystalclock - use clocking for pcm from PLL (genrated on board)

watchdog - This dual E1 Board has a Watchdog for

transparent mode

card=1,0x4, dtmf

Port settings

Syntax: <port_type>=<port_number>[,<port_number>…]

<port_type> te_ptp - TE-Mode, PTP

te_ptmp - TE-Mode, PTMP

te_capi_ptp - TE-Mode (capi), PTP

te_capi_ptmp - TE-Mode (capi), PTMP

nt_ptmp - NT-Mode, PTMP

<port_number> port that should be considered

te_ptmp=1,2,3,4

Port Options

Syntax: option=<port_number>,[,…]

master_clock - use master clock for this S/T interface

(only once per chip, only for HFC 8/4)

optical - optical (only HFC-E1)

los - report LOS (only HFC-E1)

ais - report AIS (only HFC-E1)

slip - report SLIP (only HFC-E1)

nocrc4 - turn off crc4 mode use double frame instead

(only HFC-E1)

#option=1,master_clock
#option=2,ais,nocrc4
#option=3,optical,los,ais,slip

General Options for your hfcmulti hardware

poll=

Only one poll value must be given for all cards.

Give the number of samples for each fifo process.

By default 128 is used. Decrease to reduce delay, increase to

reduce cpu load. If unsure, don’t mess with it!!!

Valid is 32, 64, 128, 256.

pcm=

# Give the id of the PCM bus. All PCM busses with the same ID

are expected to be connected and have equal slots.

Only one chip of the PCM bus must be master, the others slave.

debug=

Enable debugging (see hfc_multi.h for debug options).

dsp_options=

# set this to 2 and you’ll have software bridging instead of

hardware bridging.

dtmftreshold=

Here you can tune the sensitivity of the dtmf tone recognizer.

poll=64
#pcm=1,1

dsp_options=0

dtmftreshold=100
debug=0
