[asterisk-users] Zap FXS slow to reset?

[Scott Walde]

I have the following dialplan (segment) that isn't working as I expected 
it to:

exten => s,n,Dial(Zap/1&SIP/202&SIP/203,18)
exten => s,n,Dial(Zap/1&SIP/201&SIP/202&SIP/203,42)

The plan was to have SIP/201 added to the group of ringing phones after 
3 or so rings.  What ends up happening, though, is the Zap/1 phone STOPs 
ringing when the dialplan falls through to the second line.  The log 
reports:

Feb  4 09:20:52 WARNING[26889] chan_zap.c: Unable to ring phone: Device 
or resou
rce busy

So, it seems to me that the Zap interface isn't ready yet to take 
another call.

Is there another way I can accomplish the same thing? 
This method seems to work great when I'm dealing with all SIP phones.  
This one kind of blindsided me.

Thanks.
