...over g722 as its their preferred codec - for external calls I now set SIP_CODEC_INBOUND=ulaw to influence codec selection on calling channel and the calls set up using ulaw end-to-end Can somebody please advise how to achieve the same with chan_pjsip?

Oh, that's great. It wasn't clear from that page, at least not for me. :-( Having it clearly stated on the document would save me (and probably others) lots of time. Thanks for clarifying it.

...U/8000. a=rtpmap:101 telephone-event/8000. ... If I understand it correctly the result of codec negotiation in the above scenario should be ulaw in both call legs, thus avoiding transcoding, but actual asterisk behavior differs.

Hi, Has anybody managed to get callerid properly set on a call from local to asterisk SIP endpoint through h323-pstn gateway to a regular phone. I'm using ata186 as SIP endpoint. It has 12125551234 assigned to it. When I place a call to pstn I'm not receiving 12125551234 as the clid, but a number assigned to PRI channel by phone company. It worked with chan_oh323, but there were other

Hello, I wonder if anybody is using PJSIP realtime in production environment? I've started to play with it and encountered many problems. Here's my config: sorcery.conf: [res_pjsip] endpoint=realtime,ps_endpoints extconfig.conf: [settings] ps_endpoints => pgsql,users,pjsip_endpoints_v pjsip_endpoints_v is postgresql view. 1. The biggest problem: if I have small number of endpoints

Hi, I have asterisk functioning as SIP to H.323 gateway for local SIP endpoints and I have H.323 to PSTN gateway (Lucent MAX TNT) connecting my LAN VOIP to PSTN via PRI. Everything works fine with one exception. I seem to be unable to figure out why I cannot hear PSTN intercepted announcement ("number is not in service" etc.) when I'm calling a disconnected number through

...already here but unfortunately nothing usable happened so far (which I would know off). The priority is not high enough. I need a solution, too. I understand that this behavior is a nogo if you have a lot of calls because transcoding is expensive. Thanks Michael On 05.07.23 at 17:58 Michael Ulitskiy wrote: > Hello, > > Anyone?

Hi, I'm trying to interconnect sip and h323 endpoints using asterisk and asterisk crashes with segmentation fault whenever h323 connection needs to be established. It registers with gatekeeper ok though. Here are the symptoms. If the call initiated by SIP device, asterisk replies to it "Trying" and then silently crashes (it launched as asterisk -vvvvcd). In debug log I can see the

Hi, I've found that neither Michael Manousos patch nor ztdummy driver do not fix musiconhold sound interruption problem up to acceptable quality level. Sound is choppy here anyway. It is my understanding (please correct me if I'm wrong) that if I have a Digium card in my asterisk machine, these problems should be gone 'cause those cards provide some reliable timing. So I have no

Hello, I've started to play with PJSIP and got stuck at the following problem. I need to retrieve SIP Call-ID associated with PJSIP channel. For inbound channel I can use ${PJSIP_HEADER(read,Call-ID)}, but that doesn't work for outbound channel even in pre-dial or hangup handler. Whatever I do PJSIP_HEADER seem to be unable to read headers for outbound channel. Here's what I do:

Hi, Does anyone know if asterisk can handle 3xx SIP responces? I'm trying make it work with redirect server and it looks like asterisk isn't going to send another invite, but treats "302 Moved Temporarily" message as "Everyone is busy". Thanks. Michael

Hi, I'm wondering if there are any plans on adding secondary gatekeeper support to asterisk h323 channel drivers. Also I've noticed that chan_h323 is crashing asterisk at startup if primary gatekeeper is not available. Wouldn't it be a more correct behavior if it doesn't crashing but continue registration attempts in the background? Didn't test it with chan_oh323. Thank you.

Hi, I'm wondering if there's a way within a dialplan or AGI to find out if an extension (SIP client) is already in use and the person is already on the phone? By default the channel is assumed available and callwaiting tone is transmitted to the called extension. AFAIK there's no way to turn off callwaiting from within the dialplan. I need to avoid the callwaiting behavior in some

Hi, I guess I need some help with management interface. I would like to watch calls through the management interface, but I don't know how to identify which call an event belongs to or in other words how to associate a call and uniqueid field of event. Let's say I send the following manager command: action: originate channel: sip/12125551111@pbx1 callerid: 12125551111 MaxRetries: 1

Hello, I finally got to look at chan_sip to chan_pjsip migration again. This time I’m having problems with influencing codec selection on originating (calling) channel. It looks like PJSIP_MEDIA_OFFER only works on outbound (called) channel and has no affect on calling channel. My experiments and function documentation (which says “Media and codec offerings to be set on an outbound SIP

Hi, I don't seem to be able to get music on hold to play normally. The sound gets often interrupted with a few seconds of silence then starts playing again. I'm using mpg123-0.59r and tried mp3 files with different sample rates with no luck. If that matters, endpoints are SIP ata186, SIP Cisco 7960 and H.323 (over chan_h323) Quintum Tenor. Sometimes it may play fine for a few minutes

Hey all, I had asked a question a little while ago about CPU usage being outrageous while using tc and a cbq qdisc. Ed was very kind and offered a few suggestions. One of these was to look at hashing. So after pounding away at it for about a week, I have a general understanding of how it works and have tried to implement it. Unfortunately, and quite obviously since I''m posting here, it

Hi, I'm sorry to ask this question, but I thought I'd rather ask it here before messing up with cisco. Is anybody running cisco 7960 in redundant configuration? I mean I want the phone to be registered with both primary and backup proxy (asterisks) so that service continues to work in case of primary proxy failure. I've set in SIPDefault.cnt: proxy1_address: 192.168.1.10
