[OpenSIPS-Users] Text Message Duplication

Hi Bogdan, 

Thanks you very much for your response and time. 

You are correct. I see that there are multiple registrations of the UAC as below,

In my opensips.cfg file, I have the following config regarding usrloc module, 

# ----- usrloc params ----- 
modparam("usrloc", "db_mode", 2) 
modparam("usrloc", "db_url", 
"mysql://opensips:opensipsrw@localhost/opensips") 

Can you let me know what has to be done to resolve this issue. 

Also can you please clarify, 
1. What does the q parameter in the SDP signify? 
2. Why does the value of line param keep changing? Is it correct to have it like that? 

I am a newbie to opensips and trying to understand its working so please support me. 

Thanks and regards, 
Arjun

Hi Arjun, 

A simple explanation is that your UAC might be registered twice with opensips (has 2 records in usrloc) -> check with "opensipsctl ul show". 

If so, opensips will do parallel forking (for the received requests) to all registered contacts.

Hi All, 

Greeting to everyone!!! 

I have installed opensips 1.7.1 with RTP Proxy. I am facing the following issue, When I send a Text Message to any UAC, I receive 2 Messages instead of one at the receiver UAC. I have tried with different SIP Clients but the problem persists. 

I am newbie to opensips!! Any advice is sincerely appreciated. 

Thanks, 
Arjun
