We have a 64KB lease line from head office to regional office.
VOIP is implemented between both the locations using VIC-2FXS voice cards.
Cisco 1750-V router is used at the Head office and 3com pathbuilder router is used at the regional office.
When I make a voice call from Head office to regional office call lasts as long as we dont disconnect it manually.
But when we originate a voice call from cisco router to 3com router call establishes successfully but lasts only for 10 to 15 seconds and disconnects while we are under conversation.
Basically we have a call disconnection problem from one end.
Any workaround to solve the problem will be appreciated
