[asterisk-users] pap2 - dtmf works when 'sip debug' is enabled

[James Harper]

I am having an odd problem with a linksys pap2 ata and asterisk...
Asterisk won't detect digits from it until I issue a 'sip debug'. As
soon as I turn on sip debugging, everything works perfectly (classic
heisenbug)!

Asterisk is latest Debian 'etch' packaged 1.2.13. sip.conf looks like:

[mc_ext01]
type=friend
secret=ext01
context=mc_ata_in
host=dynamic
dtmfmode=rfc2833
nat=yes
qualify=1000
canreinvite=yes
disallow=all
allow=g729
allow=alaw

the 'dtmf tx method' on the pap2 is set to 'auto'.

Any suggestions?

Thanks

James
