[Serusers] forwarding unanswered call - once more

[Jan Janak]

Hello,

there is no special operator for it, but you could use a regular
expression to match the first line, something like this:

if (search("^SIP/2\.0 4[0-9][0-9].*$")) {
	# 4xx response
};

You will need to load textops.so module to enable this.

Note: the condition will match only requests generated by the callee --
i.e. requests that really have arrived over the network.

For example 4xx generated when fr_inv_timer hits and request is being
cancelled is generated locally and the condition will not match such a
response.

So you should do something like this:

if (search(^SIP/2\.0 4[0-9][0-9].*$")) {
     # Negative response returned
} else {
     # Request timed out
};

Note 2: I haven't tried this so it is without guarantee, let me know if
        that works or not.

 Jan.
