[Asterisk-Users] Is 3 minutes a magic number of some kind??

[David C. Troy]

All --

Having the a problem with calls cutting off after 3 minutes -- not 2:30 or
3:12, but *exactly* 180 seconds.  To illustrate, I have the following
extension:

Exten => 8005551212,1,MusicOnHold

If this extension is dialed from a Cisco 7960 (SIP), the call plays the
music, and then disconnects after 3 minutes/180 seconds exactly.

If this extension is dialed from a PSTN Zap interface, the call plays the
music, and disconnects after 3 minutes/180 seconds exactly, giving the
caller the congestion tone.

If this extension is dialed from a Pingtel Xpressa or ATA186, the calls 
stay connected after 3 min and indefinitely just fine.

Wondering what sort of value could be affecting both Zap and SIP call 
progress/timeouts, etc.  Any input appreciated.

Regards,
Dave
