[Serusers] Hairpin solutions?
by Federico Giannici 31 Aug '05

31 Aug '05

Considering that we DON'T want to use an RTP Proxy (bad scalability, waste of bandwidth and longer delays), is there any solution to the "hairpin" problems? Are there any "boxes" that look at the SIP messages and short-circuit calls from and to the local network? Thanks. -- ___________________________________________________ __ |- giannici(a)neomedia.it |ederico Giannici http://www.neomedia.it ___________________________________________________

[Users] nat flag and branch routes
by Klaus Darilion 31 Aug '05

31 Aug '05

Hi! The nat flag which will be loaded during lookup() - will it be set for each branch so it can be queried in branch_route for all of the registered contacts, or should I use isdsturiset() instead of testing for the NAT flag? regards klaus

[Serusers] Cancel'ing filure_route
by Dmitry Isakbayev 31 Aug '05

31 Aug '05

Hello, I need help understanding how to handle "CANCEL" messages. Here is the case - 1 Proxy rebuilds URI, sets 'failure_route', and executes 't_relay' 2 't_realy' times out and the proxy executes 'failure_route' after the fr_timer hits If the OUI cancels the call between steps 1 and 2, the proxy still executes the 'failure_route' after the fr_timer hits. Can I cancel any "t_on_failure" logic after receiving a CANCEL message? Or, while in in the 'failre_rout' block, can I figure out … [View More]

[Users] branchroute problem
by Klaus Darilion 31 Aug '05

31 Aug '05

Hi! In the following scenario, a call is forked to 3 phones. 2 of them are behind the same NAT (same publich IP, different port, one uses STUN, one not). I xlog all branches,dest-sets... in route[] and then in branch_route. But the branch route is executed on 2 times, instead of three times (the destination set shows that there are 3 destinations) Although the destination set is changed in the second branch processing. Is this the intended way? regards klaus route[]: request's … [View More]

Hi I've been fiddeling with the AVPops module for some time now and havn't really gotten it to work as intended. I was hoping that someone out there might be able to explain the basics of the module, cause apparently I'm misunderstanding it... I think :-) I having trouble with pulling data from my openser DB with a scheme, and then pushing (pushto) it into a request header. The thing is I cant quite figure out, if I need to store the data I get from my scheme or if I can use it directly … [View More]

[Serusers] SER's nathelper
by Frank Kostin 31 Aug '05

31 Aug '05

Hi everybody, I have two devices behind a NAT and with different codecs that can not agree upon a common codec and can not make it working. Anyone have a sample config, using SER's nathelper in conjunction with Asterisk to rewrite the SDP so that the private IP addresses are not included in the re-invite.
