OpenSIPS/OpenSER-a versatile SIP Server / Discussion / Open Discussion: 483 (too many hoops) and 403 (Rely forbidden)

Gustavo Adolfo Moennich - 2013-03-26

I just installed opensips 1.9.0 from scratch and get the following error when testing server:

root@sip:~# sipsak -T -s sip:1001@memorea.com -vv
warning: IP extract from warning activated to be more informational

0: 'no Warning header found' (0.076 ms) SIP/2.0 483 Too Many Hops
Max-Forwards set to 1
1: 'no Warning header found' (211.197 ms) SIP/2.0 403 Rely forbidden
without Contact header

Domain 'memorea.com' is configured in opensis and declared in hosts.conf (127.0.0.1 memorea.com).

What's wrong?

Thanks for help.

Hi,

Most probabaly your opensips is not recognizing the "memorea.com" as a local domain (in order to locally process the traffic) and it is looping the request.

Add "alias=memorea.com" in your cfg as global param and re-test.

Regards,
Bogdan

Thanks for reply.

I added in cfg:

alias=sip.memorea.com

and reconfigure user:

root@sip:~# opensipsctl ul show
Domain:: location table=512 records=1
AOR:: 1000
Contact:: sip:1000@sip.memorea.com Q=1

Cseq:: 1
User-agent:: OpenSIPS MI Server
State:: CS_SYNC
Flags:: 0
Cflag:: 0
Methods:: 4294967295

but 483 error persists:

Hi,

Your static registration is causing the loop - AOR 1000 (implicitly 1000@sip.memorea.com) points to contact 1000@sip.memorea.com …
