I have a new Asterisk system going into production next week and I'm a
bit stumped as to the best way to handle the Dialplans for it.

The Asterisk system is replacing 4 separate PSTN lines with both SIP &
PSTN inputs.  The setting up of the dial plan is giving me some design

this the hard way.

I have separate entire phone 'systems' for each incoming DID.  For
example, this one system will handle 4 separate incoming DIDs.  The
first (let's call it Company A) takes a call, plays a menu, gets input

for sales, 2 for support, etc.).


different company.  The incoming extension number I'm getting for this
will be entirely different, therefore will be the definition of this
phone menu structure.


then simply forward to an extension.

I have it all working fine by using:

extern => 2125551111,1,.....
extern => 2125551111,2,.....



extern => 2125551112,1,.....
extern => 2125551112,2,.....



the user becomes the extension, I then have a problem that my

what menu, etc.

I need to be able separate these into their own sections so that
extensions won't conflict but I'm not sure how to do this.  All the
calls are coming in from one SIP provider, so I have only one context
that I'm using because of that.  I'm not sure if there is a way to
create separate contexts for this and branch to them?

headaches, which probably means I'm missing something obvious and doing from the caller, directs them to the appropriate extension (ie. Press 1 The second DID has a similar setup with a menu, but its for an entirely The others are simply numbers that go through a 'Time of Day' check and etc. for the first number, and then a second set for the second number like: The problem is when I get to the Background() command to play the sound file and get the input from the user for the menu. Since the input from multi-faceted dialplan now gets confused with what extension applies to

Sure, have a top level context that inbound calls from the ITSP go into:

[from-ITSP]
exten => 2125551112,1,Goto(companya,${EXTEN},1)
exten => 2125551111,1,Goto(companyb,${EXTEN},1)

; then separate contexts for each company:
[companya]
extern => 2125551111,1,.....
extern => 2125551111,2,.....

[companyb]
extern => 2125551112,1,.....
extern => 2125551112,2,.....
