T.38 bridge fails sometimes without proxy-media
by Jeff Pyle 12 Mar '13

12 Mar '13

Hello, I'm experiencing an issue similar to Jira FS-4669<http://jira.freeswitch.org/browse/FS-4669> on 1.3.14b+git~20130306T182328Z~3e4fb4b0a2 (git 3e4fb4b 2013-03-06 18:23:28Z). The scenario at my customer's site is: XMediusFAX -> FS -> PSTN (usually Sonus GSX) or PSTN -> FS -> XMediusFAX The XMediusFAX software and the PSTN are on two different sofia profiles with the call bridged between them. Either side can send the T.38 reinvite. If the sofia profiles are configured for proxy-media, 100% of calls are successful. If the sofia profiles are not configured for proxy-media but rather only t38-passthru, approximately 50% of the calls are successful. There are no config changes between a successful and a failed call. On the failing calls the reinvite completes successfully, but FS appears not to pass the UDPTL properly. Wireshark shows only egress "Unknown RTP Version 0" where it would show UDPTL if the call were successful. In other words, the ingress UDPTL appears correct, but on failing calls the egress media does. I'm already yelling at myself for not filing a Jira yet. That's the plan, but I can't get it to fail in the lab, and the customer pcaps have too much data I'm not allowed to share. I'm wondering if anyone might have a thought about what *might* cause this so I can make sure I reproduce it in the lab accurately and file the Jira with sufficient data. - Jeff

Shared Rate Limiting?
by Avi Marcus 12 Mar '13

12 Mar '13

How do I enforce a calls per second across multiple FS machines? I can do a concurrent limit with the DB backend, that can be synced together (or be the same endpoint) but the wiki says that won't work for interval. I see a hash_remote feature, but does that only read, not increment. Perhaps the redis backend supports interval? Then I can have redis do replication. I haven't done any testing yet, it seems I'd just be stabbing in the dark. -Avi

Hi everyone, I´m new in Freeswitch and have now a simple freeswitch configuration, with one I can just make outgoings and incomings calls. I have been playing a little bit with video Calls but it doesn´t work properly. It is possible to make video calls outside the network, but they don´t come in. How do I have to do the configurations, in order to be able to have incomings und outgoings video calls? Thank you very much in advance. Best regards, SC

password for voicemail retrieval
by Archana Venugopan 12 Mar '13

12 Mar '13

Hi, Can anyone please guide me on how to set password for voicemail retrieval? Currently voicemail password is being picked from dir_users table. But I don't want to pick from that table. I either want to pick from other table or I want a default password to be set as like vm-password. Instead of creating a xml for each user in conf, can I create just 1 xml and Can I give 'vm-password' once so that for all ids this will be looked? If not can you please tell where should I change in mod_voicemail.c file so that it does not look in dir_users for voicemail. Can anyone please guide me. Regards, Archana

Quick question: What's the difference between: <action application="voicemail" data="default ${domain_name} $1"/> vs <action application="bridge" data="loopback/app=voicemail:default ${domain_name} $1"/> and why would one be used instead of the other? -- Steve
