We are trying to use SER as a NAT traversal solution in front of our Asterisk PSTN gateways and our Asterisk Feature Server. Currently, the feature server is doing all of the dialplan processing. Because of this we can have user configurable dial times, unavailability numbers, forward on busy/unavailable numbers, auto-attendants, 7-digit dialing, etc. Of course, my life would be simple if Asterisk acted more like a SIP proxy server and the dialplan could be executed somewhat like an SER routing script. Unfortunately, any call that comes from a UA to asterisk creates one call, then asterisk creates another call to the other end of the conversation (other SIP device, PSTN number, whatever), then issues reinvites to the two ends of the conversation to tell them to send RTP to each other. So what I need, is an SER script that will intelligently handle NAT traversal for UA to UA calls, UA to PSTN calls, and PSTN to UA calls (all going through the Asterisk Dialplan so we can keep all of the end user features) including the damn re-invites. Anybody had to do this before? We are quite willing to pay you for your knowledge if you want to do some design/consulting/coding work for a solution to our problem. Thanks.

[Serusers] trying to USE SER for a contact centre application

by Neill Wilkinson

All, just started using SER (great experience so far!). I'm trying to us it for a contact centre application where I have a specific requirement that calls can only be terminated in one direction, from a Cisco AS53xx gateway, not a Cisco phone. Here's the set-up and desired result: User logs into the contact centre systems which initiates a call on the PSTN side of the AS53xx. This then creates a VOIP (SIP) call leg from a dial-peer on the gateway, via the SER proxy. The agents all have Cisco 7960 IP phones which register with the SER registrar. The INVITE is proxied via a simple location lookup in the SER route[0] config file to the appropriate handset. The agent answers the call and is "logged" in to the system. Now's the fun part. I want to prevent the SIP leg being torn-down by the agent either accidentally or on purpose hanging up the call from the handset. Here's the logic (pseudo code) I have though out: Trap the BYE from the handset using a statement something like: if (method=="BYE" and uri=~"sip:[0-9]+@*") { # Agent phone initiated the BYE so do something route(1); } else { #do something else - pass on the message I guess }; route[1] { # use exec to call an external function exec_msg ('script.file'); } The external script needs to OK the BYE message - I assume use the FIFO function to construct the OK message. Now the tricky part: how do I stop the called phone from hanging up, (I tried a simple 403 Forbidden response) but that didn't work. So I thought about the REFER method with the URL of the phone sending the BYE message- can I send a refer to the Gateway (AS5300) that still thinks the dialogue is open to the phone and "hopefully" get it to send a new INVITE dialogue to the phone? Or would I have to generate a new INVITE sequence from the SER proxy exec code? If its the latter, then I need access to the RTP port number on the AS53xx from the original INVITE message - and this implies access to the SDP payload - which I can't see from the SER script (unless anyone can tell me how?) Here's a picture of what I hope to achieve!

[Serusers] Extract "from" header

by Bob Bob

Hi, I'd like to extract the From URI from a request and use it to add a Call-Info header: From: <sip:test@test.com>;tag=fd29df3df47 -> Call-Info: <;purpose=icon">http://myserver.com/get.php?id=sip:test@test.com>;purpose=icon Can it be done with ser? There are a lot of functions but none of them seem to be able to extract headers and use the information in another header. Best regards, Chris --------------------------------- Do you Yahoo!?

[Serusers] Voicemail wierdness

by Dave Bath

Hey all, Another wierdness for a sunny tuesday afternoon.... Have been using ser and * quite successfully so far, and am not into the stage of testing voicemail. Currently I am using * with mysql vm storage. I have a failure route which affter the fr_timer expires, does: failure_route[4] { # If we've got here, it means that a call timer has expired, and the user is in the # voicemail group. Therefore we're going to try and hand off the call to the Asterisk # voicemail system. revert_uri(); rewritehostport("asterisk.dev.inmarsat.com:5060"); log (1, "VOICEMAIL: VM-Divert --> Handing off to Asterisk\n"); append_branch(); append_urihf("CC-Diversion: ", "\r\n"); t_relay(); break; } This works great for normal users who are registered but not answering their phone (or indeed are busy it seems - i havent' worked out how to configure this behaviour -- any suggestions?). However, i have two problems: (1) If the call is from Nonnat UA --> SER --> Mediaproxy --> Nat UA | \/ Asterisk VM then the Nonnat UA doesn't get audio from asterisk vm. I think this has somethign to do with mediaproxy trying to proxy the vm request when it shouldnt and not knwoing where to send it - again, any suggestions? (2) The most annoying issue at the moment is for offline users. It seems logical that if you have an offline user (one that has been found in the subscriber db but just isnt' registered at the moment) you might want their address to divert to vm. However, no amount of fiddling has enabled be to use a failure route for this, and i'm not sure why. In desperation i just created a new route block to handle it - the same as above, but called route[4] instead of failure_route. This at least forwards the request correctly. However, all i get is "The p...." and then the media stream cuts out, and * console shows the channel has been hung up. Below is the ngrep. For some reason two INVITE reuqests are sent from ser(.136) to *(.137) and i'm not sure why. Notice also that a CANCEL is generated, which corresponds to the media stream dying almost as soon as it starts, but again i'm not sure why.... If anyone has anyideas... if you need to look at the ser.cfg then let me know. I'm sure there must be a mor elegant way of handling vm but im not sure what it is at the moment!

[Serusers] Problem with Asterisk VM + MySQL Database

by TSS Support

We are trying to use the MySQL database for voicemail logins. I can see that * connects correctly to the database and is executing queries, so I'm pretty sure I got the config right. However, it doesn't seem to be picking the password up properly. Found a couple of old mailing list messages about this but no solution. Anyone seen this before and can help me figure out what I'm missing? Here's the info: Relevent debug statements from * vm:/etc/mysql# asterisk -vvvvvvvvvgrc == Parsing '/etc/asterisk/asterisk.conf': Found Asterisk CVS-05/31/04-22:00:51, Copyright (C) 1999-2004 Digium.

I just updated and rebuilt my SEMS source from cvs. SEMS starts ok but when an inbound calls is relayed to SEMS I get a reorder tone and the following log messages. I didn't see any mention of this in the list archives. Can someone explain what is happening? Thanks,Steve 8396@128.91.50.49:5060>> Aug 23 14:20:15 voicesrvr ser[28966]: [SER_vm]: URI match.
