extract domain from SIP URI
by Jayesh Nambiar 07 Apr '10

07 Apr '10

Hi, Is it possible to identify the domain part in an incoming R-URI by using some built-in variable in Freeswitch? For eg. if a call comes into freeswitch as vmail(a)domainA.com, can i use something like "sip_h" to extract the domain part of the R-URI? Thanks in advance, w/regards, Jayesh.

Join XML dialplan configuration (local/XML_CURL)
by Gianluca Varisco 07 Apr '10

07 Apr '10

Hello guys, I tried to set up a brand new installation of FS 1.0.6 so that it reads dialplan configs from XML_CURL module and from local files. No troubles so far with it. I neeed to know how to set my freeswitch configuration in a way that my dialplan takes a common part from the local files and a user specific part from an external URI (via XML_CURL). At the moment I've a working configuration with both local and XML_CURL correct responses. Any suggestion on ways to join the two parts is appreciated. Many thanks. Gianluca

SLA/BLA issue(sofia_presence.c:2139 Gateway information missing)
by Bryan 07 Apr '10

07 Apr '10

Hi, I'm testing SLA/BLA feature with Freeswitch, but failed. Could you tell me what's wrong ? I see that both the server and the phone subscribe to each other, but the last NOTIFY from the phone to the server gets rejected with "Call does not exist". On the console I get the following error message: [ERR] sofia_presence.c:2135 Gateway information missing. Thanks. Bryan

SRTP on FreeSWITCH
by SERGE TUMBA 07 Apr '10

07 Apr '10

Dear All, I know that FreeSWITCH supports ZRTP but I would like to know if someone already tried to deploy SRTP on FreeSWITCH? If so, can I have the HOWTO describing this setup if any have been done? Thank you! Serge. _________________________________________________________________ The New Busy is not the old busy.

Security mesurement
by SERGE TUMBA 07 Apr '10

07 Apr '10

When comparing ZRTP sessions with sessions that do not involve ZRTP, and seeing if there are performance differences that affect usage scenario. In other world, comparing the situation where zfone encrypt two end points and the situation where no zfone is used. What tools (security tools or network tools or any others) can help to perform this task and how to come up with performance differences. Thank you!

Protection with ZRTP
by SERGE TUMBA 07 Apr '10

07 Apr '10

I know that in ZRTP, the negotiation of the cryptographic keys takes place entirely in the RTP stream. However, I do not understand: 1. How can this be proven when having setup FreeSWITCH and having deployed ZRTP, and having two softphones (such as X-LITE) connected in a test environment. Can a tool cush as Wireshark or any other be used in this case? 2. What are other protection mechanisms provided to prevent third-parties from masquerading as one of the end-points? Thank you! Serge. _________________________________________________________________ The New Busy think 9 to 5 is a cute idea.

ZRTP protocol measurement
by SERGE TUMBA 07 Apr '10

07 Apr '10

I would like to know how to measure the performence of the zrtp using FreeSWITCH that connect two X-Lite softphones which use the zfone for encrypting voice packets on both end phones. Also, can someone contrast and compare ZRTP to SRTP focusing on these two protocol behaviors. Thank you! _________________________________________________________________ The New Busy is not the old busy.

SIP Overlap support?
by Dennis 06 Apr '10

06 Apr '10

hi there, i would like to ask, if fs has support for something like "SIP Overlap"? instead of receiving the phonenumber from our carrier in a block, we want to receive the phonenumber digit-by-digit and we want to tell fs when the number is complete. our carrier could send us the phonenumber digit-by-digit, but what about the fs-side? thanks and kind regards dennis
