Hi Ozan,

first, if you want not to account SIP2SIP calls, you have just not to 
set the acc flag for those calls (flag 1 in your script). In other 
words, if you want to account only calls going to PSTN, set the flag 1 
only if destination is PSTN.

Regarding the BYE - this is an well known issue and you can solve it on 
the GW side (depending what GW you have) - you may enable on your GW two 
types of timers:
    - for received media: if the GW received no more media in X secs, it 
will generate the BYE.
    - Session Timer: periodically, the GW probes if the UAC is still on 
by sending reINVITEs - in case of no answer or negative reply, a BYE is 
generated.
Take a look at your GW specification if it has support for this.

Since the BYEs generated in this case by GW will end by timeout (the 
client being disconnected), note that you need to enable 
"failed_transaction" acc param (set it to on) in 0.9.x  or set a flag 
for "failed_transaction_flag" acc param in 0.10.x (see the online doc 
for more info).

For PostPaid - it's welcome - when you have a working version, please 
let us know and we can arrange with the upload.

regards,
bogdan
