[Asterisk-Users] Speeding up UK BT incoming call detection

[Richard Dutton]

Hi,

I am running Asterisk v1.2.7.1 with a Digium TE110P. My dialplan is very
simple, when a call comes in on my analogue BT PSTN line, it rings the other
ZAP interface (my house phone). Slightly pointless (having a 1x1 switch) I
know, but I am planning on doing more with internal SIP extensions, and
outgoing SIP services etc.... At the moment it's just simple though whilst I
try to fix this problem.

My problem is that it normally takes 2-3 rings on an incoming call before
Asterisk detects the line ringing and then a further 2 rings before it
starts ringing my phone. I know this because I have plugged a normal
analogue phone into another extension of the BT line as my Asterisk
connected phone starts riniging about 4 or so rings later!

Can anyone tell me what the optimal settings for zaptel.conf and zapata.conf
for a BT line or have any other suggestions to try and speed things up? 

Cheers
