Hi Bogdan,
I'm working with Mickael about this problem, and we have some informations
which may help you (and then help us ;-) ) :
We have found that "loose_route" function modify the Request-URI variable
($ru), as you can see below :
ACK message comes from provider, with $ru = sip:+333XXXXXXXX at 6.6.6.6
After, loose_route function is executed, and $ru become like $ru
= sip:7.7.7.7;lr;r2=on;ftag=c97942d9-13c4-503ca77b-ef8c9eef-760f27a5;xyz=c12.18aedaa5
The last $ru value results from a Route header
For information, Record-route of previous message (200OK) is composed with
two record-route in the same field, comma separated.
Is Opensips 1.6.4 able to interpret this type of Record-route ?
Is loose_route function using Route headers of previous messages (200OK
before ACK) to route this message ? Or is it using only actual message's
Route headers ?
Thanks in advance,
If you need further informations, feel free to ask us.
