$route.underlimit method - specify response

[vinylmike]

1. Brekeke Product Name and Version:
3.2.4.3 Advanced

2. Java version:
1.6.0_45-b06

3. OS type and the version:
RHEL 5

4. UA (phone), gateway or other hardware/software involved:


5. Your problem:
Using the $route.underlimit method, when the limit is reached I see a "404 Not Found" is sent back to the UA. Is there a way to configure what failure response is sent back, i.e. like 503 Service Unavailable?

Matching Patterns

$request = ^INVITE To = sip:(\+)(1203)(.+) $route.underlimit( "%2", "2" ) = true

Deploy Patterns

$routename = %2 $continue = true

Thanks,
Mike

Matching Patterns

$request = ^INVITE To = sip:(\+)(1203).+ $route.underlimit( "%2", "2" ) = false

Deploy Patterns

$response = 503

James,

Thanks, but when I use that plan false is never returned as a value, regardless of how many concurrent calls I make through the server, e.g. with 4 concurrent sessions the following is still returned:

Pattern: $route.underlimit( "%2", "2" ) = false
Input: $route.underlimit( "1203", "2" ) = true
Result: false

Thanks,
Mike

[hope]

is the call applied rule with route.underlimit?
put reject rule under the rule with underlimit is true

[vinylmike]

Hope/James,

Thanks for the help. I was able to accomplish this using two dial plan entries:

1st

Matching Patterns

$request = ^INVITE $addr = ^172\.16\.2\. To = sip:(\+)(1203)(.+) $route.underlimit( "outbound", "2" ) = true

Deploy Patterns

$routename = outbound $continue = true

2nd

Matching Patterns

$request = ^INVITE $addr = ^172\.16\.2\. To = sip:(\+)(1203)(.+) $if($route.underlimit( "outbound", "2" ), "true", "false") = false

Deploy Patterns

$routename = outbound $action = 503

This works as expected, however if you can think of another way to do it, or by combining the two entries into one, I'm all ears.

Regards,
Mike

Changed a little.


Rule-1:

Matching Patterns

$request = ^INVITE $addr = ^172\.16\.2\. To = sip:\+1203.+ $route.underlimit("outbound","2") = false

Deploy Patterns

$response = 503

Rule-2:

Matching Patterns

$request = ^INVITE $addr = ^172\.16\.2\. To = sip:\+1203.+

Deploy Patterns

$routename = outbound $continue = true

Thanks JanP.

One more question -

When the concurrent call limit is reached and dial plan rule returns the 503 I don't see any evidence of that in the Brekeke server logs. I can can only see the SIP response when using a sniffer (wireshark / tcpdump). Is there a way to expose this so it's logged for later reviewing?

I noticed the same issue exists when also using the $sps method.

Thanks,
Mike

[hope]

is it in error log page?

[vinylmike]

Ahh, indeed it is , on our >3.2.2.3 version hosts. That'll work, thanks!

If you use $log in Deploy Pattern, you can write own log message in sv.xxx.log file.

Find "$log" in the http://www.brekeke.com/doc/sip/sip_admin_v3.pdf

For example...

Deploy Patterns

$response = 503 $log = WARNING! Call limit is reached!! Return 503 to %{$addr}.
