Thanks for the pointer, Eric. For anyone else trying this, I simply  
edited /usr/src/zaptel/wctdm.c and changed "static int boostringer =  
0;" to "static int boostringer = 1;" (Changed the 0 to a 1). Then,  
stop Asterisk, unload zaptel, recompile zaptel, and then reload  
zaptel and reload Asterisk. For those using Asterisk at Home:

1.) log in as root
2.) edit /usr/src/zaptel/wctdm.c
3.) /usr/sbin/amportal stop (This stops Asterisk)
4.) service zaptel stop (This unloads Zaptel)
5.) rebuild_zaptel
6.) service zaptel start (This reloads Zaptel)
7.) /usr/sbin/amportal start (This starts Asterisk again...)

Of course, you could just issue a rebuild_zaptel command and reboot,  
but where's the fun in that?

The change seems to have improved the ringer, but it still isn't as  
good as a Verizon POTS line. Also, I still cannot get pulse dialing  
working properly. It seems to work somewhat, but certainly not  
reliably. Often, I can dial another extension on my PBX and it will  
ring, but the old pulse phone actually gets a second dialtone in the  
receiver, as if I had flashed the switchhook. If I do indeed flash  
the switchhook twice, I am connected to the dialed extension,  
assuming that they picked up.

Any ideas why my zapata is ignoring the pulsedial=yes directive?

Does anyone know of an ATA that supports pulse dialing?
