SIP - registering a E1

Unanswered Question

Hi! I have a problem with my ISP and SIP commiucation.


Incoming call (SIP) come to me from ISP, my router translate call to PBX (e1 channel). But - I have a problem with registering PBX-number on a ISP side. If I have a ephone with requared number - no problem with calls, my ISP say that my phone registered successful, but - if I assign this number to pots E1 - It can't be registered.

My config is:



authentication username 5555555 password 1111

registrar ipv4: expires 3600

sip-server ipv4:



dial-peer voice 1 voip

descrip =TO-ISP=

destination-pattern .T

session protocol sipv2

session target sip-server

session transport udp

dtmf-relay h245-alphanumeric

codec g711alaw

fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback none



dial-peer voice 1 pots

destination-pattern 5555555

no digit-strip


port 0/2/0:15

authentication username 5555555 password 1111

For SIP registering, there will be a new CLI 'sip-register' or 'no sip-register' that will do the job. Try this
