New subject: How to add some text at end of body line with subst_body

25 Feb 2014

Hi,
I'm trying to add some string at the end of some line in the body/sdp of a SIP INVITE
for testing some interoperability.

The following line
a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:NwC8z5MsyCWbpJJo1n2BDS8DkGuUU2cIt9KRUqPU

should be converted to

a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:NwC8z5MsyCWbpJJo1n2BDS8DkGuUU2cIt9KRUqPU
UNENCRYPTED_SRTCP

I tried with this:

subst_body('/(a=crypto.*)\r/\1 UNENCRYPTED_SRTCP\r/g');

but it does not match

just using

subst_body('/(a=crypto.*)/\1 UNENCRYPTED_SRTCP/g');

matches but results in this (carriage return between key and
"UNENCRYPTED_SRTCP"):

a=crypto:1 AES_CM_128_HMAC_SHA1_80
inline:NwC8z5MsyCWbpJJo1n2BDS8DkGuUU2cIt9KRUqPU\rUNENCRYPTED_SRTCP

using Kamailio 3.3.6

Any ideas?

Mit freundlichen Grüßen / Best regards
