[SIPForum-discussion] Regarding Trigger Point

[rupandeep singh]

Thanks Rajdeep for this information but one more thing i want to ask....
The m-line can have any number of codecs in it and each codec has a a line , so for each line we have to perform a search, than how can we create a SPT for m line or a line as there number are variable and also each time codecs used can be different.

And can you please elaborate what do u mean by regular expressions and string ie. the entire value of the line .

Regards 
Rupandeep

the regular expression shall be matched with the string received in
the INVITE message
