Hi Mojtaba,

not looked in the code – but it could be related to be able to check with this function for request and replies. Replies will have the method name in their CSEQ.

If you have a requirement that is not available right now in the module, it can be of course extended (e.g. by pull request).

Cheers,

Henning

Hello,

Some confusing things while developing in Kamailio:

In is_method_f function in textops module, the code checks the HDR_CSEQ_F in msg also, and if the method name appears in CSEQ_F, The result is returned TRUE.

These question will  arise why in this function, the CSEQ field in message will check?

if(parse_headers(msg, HDR_CSEQ_F, 0)!=0 || msg->cseq==NULL)

{

LM_ERR("cannot parse cseq header\n");

return -1; /* should it be 0 ?!?! */

}

if(m->s==0)

return (get_cseq(msg)->method_id&m->len)?1:-1;

else

return (get_cseq(msg)->method_id==METHOD_OTHER

&& get_cseq(msg)->method.len==m->len

&& (strncasecmp(get_cseq(msg)->method.s, m->s,

m->len)==0))?1:-1;

I think it would be nice to add new function like: is_cseq_method_f in module to avoid some problem understanding.
