Pjsip syntax error exception when parsing request line header on line 1 col 1

Getting this error on a fully updated FreePBX system for one extension.

Anyone seen this before? Is this simply packet corruption?

Just confirmed that calls to this extension work, but calls from it do not.

We just might need to summon @JaredBusch to help you.

I’ve never had that error to my knowledge.

I just ran grep on the logs of a few PBX systems to check. Nothing found.

It’s my first time running into it. Wondering if it might not be a corrupted client.

Похоже, подключение к MangoLassi было разорвано, подождите, пока мы пытаемся восстановить соединение.

Difficulties when connecting via Proxy #172

Hello, I’m trying to install FreePBX inside a Portainer and I can make all connections to port 5060 normally, they all arrive at FreePBX but I’m having problems with the request headers (I’m testing via applications like Zoiper), see:

What happens externally is that a different machine, using Nginx, is trying to make a Proxy Pass for this one, apparently my Nginx is damaging the header (?), Is there any way to solve this?

Below my configuration on Nginx:

I don’t have much experience with this, I just tried to follow several tutorials on the internet and I was stuck here for a few days.

The text was updated successfully, but these errors were encountered:

Не совсем понимаю, что означает и как полечить вот эту проблему. Догадываюсь, что где то в настройках пира, но не нахожу где.
То же самое подключение по SIP протоколу проходит успешно

When using Kamailio from the master branch, I’m encountering an issue where IPv6 contact address aliases that are added via set_contact_alias() for WebSocket connections (for example) are unquoted and create problems for Asterisk:

pjsip:0 <?>:    sip_transport. Error processing 3633 bytes packet from UDP 10.0.0.1:5060 : PJSIP syntax error exception when parsing 'Request Line' header on line 11 col 129:

and TOPOH garbles the Request-URI when processing the ACK:

WARNING: sanity [sanity.c:236]: check_ruri_scheme(): failed to parse request 
uri [�a�{1me▒s�na@50�9���1.�8:�2v0;i��a��=11>7�n7x>10O�2v0~1]

I have tested this with CSipSimple nightly branch (PJSIP) Asterisk 13.2.0 (PJSIP), Google Chrome 41.0.2272.118, and Firefox 37 and all fail to handle the Contact alias parameter properly.

An example of an invite that shows this issue follows (this INVITE is without TOPOH on).

I believe that the Contact header alias parameter might need quotes in order to properly handle the bracketed IPv6 alias address, something like the following, but unfortunately I haven’t been able to find evidence to be certain that this is the fix, though I do notice that parameters in headers with special characters like brackets are often quoted.

Pjsip syntax error exception when parsing request line header on line 1 col 1

Getting this error on a fully updated FreePBX system for one extension.

Anyone seen this before? Is this simply packet corruption?

Just confirmed that calls to this extension work, but calls from it do not.

We just might need to summon @JaredBusch to help you.

I’ve never had that error to my knowledge.

I just ran grep on the logs of a few PBX systems to check. Nothing found.

It’s my first time running into it. Wondering if it might not be a corrupted client.

Похоже, подключение к MangoLassi было разорвано, подождите, пока мы пытаемся восстановить соединение.

Pjsip syntax error exception when parsing request line header on line 1 col 1

welcome to the Polycom Community.

The SPIP550 should be on UC Software 4.0.11 and not 4.1.1 as this is for LYNC only.

I suggest you post your configuration and try and get some logs of the VVX Phone.

  • Settings > Logging > Global Log Level Limit > Debug
  • Settings > Logging > Log File Size (Kbytes) > 160
  • Settings > Logging > Module Log Level Limits > SIP > Debug
  • Settings > Logging > Module Log Level Limits > TLS > Debug
  • Settings > Logging > Module Log Level Limits > CURL > Debug

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Difficulties when connecting via Proxy #172

Comments

Hello, I’m trying to install FreePBX inside a Portainer and I can make all connections to port 5060 normally, they all arrive at FreePBX but I’m having problems with the request headers (I’m testing via applications like Zoiper), see:

What happens externally is that a different machine, using Nginx, is trying to make a Proxy Pass for this one, apparently my Nginx is damaging the header (?), Is there any way to solve this?

Below my configuration on Nginx:

I don’t have much experience with this, I just tried to follow several tutorials on the internet and I was stuck here for a few days.

Asterisk почему-то это поле Contact не нравится , и он в консоли он выдает ошибку:

Т.е. с таким полем Contact все работает
